Chapter 4 deep foundation ( bi )
This document provides an overview of deep foundations and pile foundations. It discusses factors that affect foundation design such as building loads and soil bearing capacity. Deep foundations transfer loads below the ground floor level, usually more than 3m below grade, and include pile foundations. Pile foundations transmit structural loads to deeper subsoil using columns inserted into the ground. Pile types include displacement piles (driven into the ground), replacement piles (bored into place), and composite piles (using multiple materials). The document also describes pile installation methods, classification of piles, advantages and disadvantages of different pile materials, and pile driving techniques.
BASIC CIVIL ENGINEERING
This document provides an overview of foundations for civil engineering structures. It defines foundations as the substructure below ground level that supports the superstructure above. Foundations distribute structural loads over a large area of soil to prevent excessive settlement. There are two main types of foundations: shallow foundations, which are less than the width in depth; and deep foundations, which extend deeper. Shallow foundations include isolated footings for columns and combined footings for groups of columns. Deep foundations include pile foundations, which transfer loads using friction or bearing on a hard stratum, and pier foundations. Piles can be made of concrete, steel, or timber and installed using methods like driving, jacking, or drilling.

This document provides information on pile foundations, including when they are used, their functions, types, and construction methods. Pile foundations are used when the soil at shallow depths does not have adequate bearing capacity. The key points are:
- Pile foundations transmit loads from structures to deeper, stronger soil layers through end bearing, friction, or both.
- They are used when shallow soils cannot support heavy loads, have low bearing capacity, or experience issues like high water levels.
- Piles can be made of concrete, timber, steel, or composites, and are either pre-cast or poured in place. Common types include end bearing, friction, compaction, and anchor piles.

Shallow foundation
This document discusses shallow foundations. Shallow foundations are placed at a shallow depth and distribute structural loads over a wide area. The main types of shallow foundations are spread footings, combined footings, mat/raft foundations, and grillage footings. Spread footings support columns and walls and transmit loads to the soil. Common varieties include wall, reinforced concrete, inverted arch, and column footings. Combined and mat foundations are used when columns are close together or loads are large. Shallow foundations provide quick construction and resist water absorption but have limitations with point loads.
Foundation and its types
The document discusses different types of foundations for buildings. It describes shallow foundations, which transfer loads to depths of less than 3 meters, including spread footings, strip foundations, mat foundations, and combined footings. It also describes deep foundations, which transfer loads to depths greater than 3 meters, including pile foundations and caisson foundations. Key factors for determining the appropriate foundation type include the soil bearing capacity and required load capacity of the structure.

This document discusses types of deep foundations, including piles. It describes bored piles and driven piles. Bored piles can penetrate obstructions like boulders better than driven piles. They also allow adjusting the length and diameter. However, bored piles have defects like contamination, voids, and necking. Driven piles compact the surrounding soil and increase capacity. Factors like subsurface conditions, noise levels, and material availability influence pile type selection. Timber and precast concrete are common pile materials. Timber piles have a high strength but their portion above groundwater is susceptible to decay. Precast concrete piles are used in marine structures where cast-in-place piles are impractical.
Foundation of a building
1) Foundations are the lowest part of a building structure and come in several forms including pad stones, stone foundations, rubble trench foundations, shallow foundations like spread footings and slab-on-grade, and deep foundations that transfer load down through weaker topsoil.
2) Common shallow foundations are spread footings and slab-on-grade foundations, while deep foundations include piles, drilled shafts, caissons, and earth stabilized columns to transfer load below the frost line.
3) Monopile foundations use a single large-diameter pile embedded into the earth to support all loads of large above-ground structures and have been widely used for offshore wind farms.
Pile Foundation
Piles have been used for foundations for centuries, initially using timber driven into the ground. Over time, pile driving machinery improved and steel and concrete piles came into use. Piles transfer structural loads to deeper, stronger soil layers, preventing failures in weak surface soils. They are commonly used when expansive or collapsible soils are present, for offshore structures, and near waterways prone to erosion. Piles can be made of wood, steel, concrete, or composites of multiple materials. They are classified based on load transmission, material type, and their effect on surrounding soils during installation. Modern pile foundations employ a variety of techniques to provide strong, durable support for structures in difficult soil conditions.
PILE FOUNDATION-INDIA
This document discusses pile foundations. Piles are structural members made of materials like steel, concrete, or timber that are driven into the ground to support buildings on weak soils. There are two main types of piles: end bearing piles that extend to bedrock, and friction piles that gain support through friction in the soil when no bedrock is present. Pile caps are used to distribute loads from the structure to multiple piles. Reinforcement in the pile cap resists tensile and shear forces. The document provides schematics and comparisons of different pile foundation construction methods.
Types of foundation
The document discusses different types of foundations, including shallow foundations, deep foundations, and pile foundations. Shallow foundations have a depth less than the width and include spread, wall, isolated, combined, and continuous footings. Deep foundations have a depth greater than the width. Pile foundations transfer load to deeper, stronger soil layers using reinforced concrete, steel, or timber piles that are driven into the ground. Piles can be classified based on their function as end bearing, friction, or under-reamed piles.

Advantages and disadvantages of precast piles are also summarized.
DEEP FOUNDATION
Deep foundations are used when the bearing stratum is located at a significant depth below the surface. The most common types of deep foundations are pile foundations, cofferdams, and caisson foundations. Pile foundations support structures using vertical piles that transfer loads either through end bearing or skin friction. Piles can be made of timber, concrete, steel, or a composite. Cofferdams are temporary structures used to exclude water from a construction site to allow work below the water level. Common types include earthfill, rockfill, single-walled, and cellular cofferdams. Caissons are watertight structures that become part of the permanent foundation. Types are open caissons, box caissons

There are two main types of foundation systems - shallow and deep. Shallow foundations include spread footings and mat/raft foundations. Spread footings are individual slabs under columns and walls that spread the structural load over a broad area. Mat/raft foundations use a continuous slab over the entire loaded area and are often used for structures with high or irregular loads. Deep foundations include piles, piers, caissons and compensated foundations that extend below the building. Piles transfer structural loads to stronger soils at depth using end bearing or friction along the pile. Common pile types include concrete, steel and timber piles.
Building Foundation
About foundation and its Types
1. Foundation, Part of a structural system that supports and anchors the superstructure of a building and transmits its loads directly to the earth.
2. To prevent damage from repeated freeze-thaw cycles, the bottom of the foundation must be below the frost line.
3. The foundations of low-rise residential buildings are nearly all supported on spread footings, wide bases (usually of concrete) that support walls or piers and distribute the load over a greater area.
4. A concrete grade beam supported by isolated footings, piers, or piles may be placed at ground level, especially in a building without a basement, to support the exterior wall.

Pile foundations use driven or bored piles to transfer structural loads to deeper, load-bearing soil strata. Piles are classified by their function (end bearing, friction, anchor piles), material (timber, concrete, steel), and installation method (driven, cast in situ). Pile foundations are used when bearing capacity is limited at shallow depths or in unstable soils like waterlogged or compressible soils. Selection depends on factors like subsurface conditions, structural loads, groundwater levels, and material availability and costs.

Recent Trends in Pile Foundations Auger Cast Piles for Low Noise / Low Vibration
Recent Trends in Pile Foundations Auger Cast Piles for Low Noise / Low VibrationAmerican Society of Civil Engineers, Orange County Branch
"Recent Trends in Pile Foundations Auger Cast Piles for Low Noise / Low Vibration" presented by Nick Briffa, PE, Group Delta Consultants to ASCE OC Cast in situ Pile
Cast in situ piles are concrete piles that are constructed by excavating soil and pouring concrete directly into the hole. There are several types of cast in situ piles including simplex, franki, and vibro piles. The simplex pile is most common in Bangladesh. To construct a simplex pile, a casing is installed and reinforced with rebar before concrete is poured into the casing while it is vibrated out of the ground. Cast in situ piles are preferable to driven piles in areas with noise limitations, existing structures nearby, or weak and loose soils. The construction process involves soil testing, boring, installing rebar cages, and pouring concrete through a tremie pipe.

It discusses 12 different causes of foundation failures including load transfer failures, drag down and heave in expansive soils, collapsible soils, lateral loads, construction errors, unequal support, water level fluctuations, earthquakes, vibrations, landslides, uplift, and concludes with recommendations. Preventative measures include soil improvement techniques, structural options like piles, quality assurance in mitigation, and construction controls. Remedies include underpinning, soil nailing, and preventing differential settlement.Economic order quantity (eoq)
The document defines and explains economic order quantity (EOQ), which is the order size that minimizes the total costs of ordering and carrying inventory. EOQ is determined using the Wilson formula, which balances ordering costs (such as transportation and staff costs) against carrying costs (such as capital costs and storage fees). The document also provides examples of an aging schedule, which classifies inventory by age to help identify slow-moving items and better manage inventories.
3...economic order quantity
The document discusses the economic order quantity (EOQ) model, which determines the optimal order quantity that minimizes total inventory costs. It defines EOQ as the order size that balances holding costs from carrying inventory with ordering costs. The document provides the EOQ formula and explains its underlying assumptions, as well as how to calculate EOQ and examples of its applications for organizations.
Economic order quantity
1. Economic Order Quantity (EOQ) is a model that determines the optimal order quantity to minimize total inventory costs, which include ordering costs and carrying costs. It balances placing frequent small orders with less inventory against placing infrequent large orders with more inventory.
2. The basic EOQ formula is the square root of 2 times annual demand times ordering cost divided by annual carrying cost. There are variations that incorporate factors like production rates, backorders, quantity discounts.
3. To use EOQ, calculate costs of ordering and carrying inventory, inputs like demand and costs, then apply the formula to determine the optimal order quantity. Graphing the costs can help visualize the minimum total cost point.

Module 3 pile types and construction
Pile types can be classified based on function, material, or construction method. Common pile types include end bearing piles, friction piles, and composite piles made of different materials. Piles are also classified as concrete piles, which can be pre-cast or cast-in-situ, timber piles, steel piles like H-piles or pipe piles, and composite piles combining materials. Construction methods include displacement piles that displace soil during installation and replacement piles that extract soil to form the pile shaft.
Caisson foundation.ppt
This seminar report discusses caisson foundations. Caissons are watertight structures used for deep foundations under water, such as for bridges, piers, and docks. There are three main types - open, box, and pneumatic caissons. Caissons can take various shapes and are used when foundations need to extend below riverbeds or in deep water. Advantages include ability to reach large depths, but difficulties include tilting or sinking during construction. Caisson diseases can affect workers if decompressed too quickly from pressurized conditions.
BUILDING MATERIALS - SAND
Sand is a naturally occurring granular material composed of finely divided rock and mineral particles, with silica being the most common constituent. There are different types of sand sourced from pits, rivers, seas and dredging, with each having distinct properties that make them suitable for different construction applications like plastering, masonry or concreting. Proper testing and grading of sand ensures it meets the necessary quality standards for use in various building works.
Construcción de obras (pilotes)
Pilotes son elementos constructivos utilizados para cimentaciones profundas cuando los estratos superficiales del suelo no soportan las cargas de la estructura. Se usan para soportar cargas verticales u horizontales mediante rozamiento y resistencia a la penetración. Históricamente se usaron en Venecia, y los españoles adoptaron el término al ver viviendas indígenas sobre pilotes en Venezuela.

Pile foundation ppt
This document provides information about pile foundations. Pile foundations are used when the soil cannot support building loads and piles are driven deep into the ground until they reach a bearing stratum. Piles can be made of timber, concrete, or steel. They transfer loads from the building to the stronger subsurface layer. The document discusses different types of piles including end bearing and friction piles and explains how pile caps are reinforced to resist tensile and shear forces from heavy loads. Diagrams show how pile foundations are arranged and how piles transmit loads into the ground.

FOS = Allowable Pile Capacity / Design Load
FOS for piles = 3 (for piles in clay)
FOS for piles = 2.5 (for piles in sand)
Higher FOS for piles in clay due to higher variability in strength compared to sand.

Types of deep foundation
There are several types of deep foundations that can be used depending on the soil conditions and load requirements. These include basement foundations, buoyancy raft or hollow box foundations, well/caisson foundations, pier foundations, drilled shaft foundations, and pile foundations. Each type has advantages and disadvantages related to cost, construction difficulty, and suitability for different soil and loading conditions. Common examples of deep foundations used include caissons for bridge piers, drilled shafts for structures with large axial and lateral loads, and piles beneath structures with high groundwater or compressible soils. The type of deep foundation selected depends on the project needs and subsurface environment.

building foundation kagemu SELEMANI
This document provides information on foundations for buildings. It defines foundations as the lowest part of a structure that transfers loads to the soil. Foundations have several functions, including distributing weight over a large area to prevent overloading the soil. Proper site investigation is important to determine soil properties and suitable foundation type. Investigation methods include test pits, auger borings, and deep borings. Bearing capacity refers to the load a soil can support without excessive settlement. Shallow foundations suitable for stronger soils include strip, raft, and pad foundations. Deep foundations using piles are used for weaker soils.
Types Of Foundation
The document discusses different types of foundations for structures, including shallow and deep foundations. It describes spread footings, mat/raft foundations, piles, piers, and caissons. Spread footings are the most common shallow foundation and involve concrete slabs under columns and load-bearing walls. Mat/raft foundations use a continuous slab to spread loads over a large area, especially for high loads or poor soil. Deep foundations like piles, piers, and caissons extend deeper into the ground to bear loads in stronger soil layers. Piles transfer loads through end bearing or friction, while piers and caissons are constructed by excavating holes and filling with concrete.

It begins by defining what a foundation is and its purposes, which include distributing the load of the structure, preventing differential settlement, and providing stability. It then covers factors that affect foundation design like soil conditions, structural requirements, and cost. The main types of foundations discussed are shallow foundations, which transfer load directly to the soil, and deep foundations, which transfer load deeper using techniques like piles. Construction of foundations involves site preparation, excavation, forming and pouring footings and walls. The document also discusses underpinning existing foundations and protecting foundations from moisture using waterproofing and drainage.
Foundation
Foundations transmit loads from buildings to the ground below. There are different types including shallow foundations like spread footings and deep foundations like piles. Spread footings support individual columns on isolated slabs while combined footings link two columns. Strap footings connect isolated footings with a beam. Mat foundations are large slabs supporting many columns. Pile foundations transfer loads to deeper soils through friction or bearing. Foundations can fail due to unequal settlement, subsoil moisture movement, lateral pressures, or weathering effects. Proper design and construction seeks to prevent these failures.
Foundations grp 1
Raft foundations are large concrete slabs laid on the ground to support buildings. They spread the building load over a wide area, lowering pressure on the soil. This makes raft foundations suitable for unstable soils, areas with soil movement, and buildings with high loads or closely spaced supports. Raft foundations can serve as both the foundation and floor slab. They are used for heavy commercial buildings, in low bearing soils, and where footing overlap would otherwise occur. Advantages include reduced excavation needs and differential settlement.
pile wall

Liquid limit is the water content where the soil starts to behave as a liquid. Liquid limit is measured by placing a clay sample in a standard cup and making a separation (groove) using a spatula. The cup is dropped till the separation vanishes. The water content of the soil is obtained from this sample.
EXCAVATION FOR FOUNDATION - Methods & Temporary Earth Retaining Structures
Generally excavation means to loosen and take out materials leaving space above or below ground. Sometimes in civil engineering term earthwork is used which include back-filling with new or original materials to voids, spreading and leveling over an area.
