Standard Penetration Test for soils
The document describes the standard penetration test (SPT) method for determining the bearing capacity of soils. SPT involves driving a split spoon sampler into the soil using a 63.5 kg hammer dropped from a height of 75 cm. The number of blows required to penetrate each 150 mm interval is recorded as the N-value. N-values are corrected for overburden pressure and dilatancy. Bearing capacity is then calculated using corrected N-values, soil properties like internal friction angle, and factors for shape, depth, inclination, and water table location. The SPT provides soil strength data and undisturbed samples needed to determine cohesion and friction angle for bearing capacity calculations.

Pvd Soil Consolidation Design
Prefabricated vertical drains (PVDs) are synthetic drains used to accelerate consolidation of soft soils. PVDs shorten drainage paths, reducing consolidation time from over 15 years to 1 year. PVDs are more efficiently installed than sand drains, with lower risk of breakage or shear failure during installation or settlement. PVDs have higher discharge capacities than sand drains and cause less soil disturbance during installation, resulting in smaller smear zones. Properly designed and installed PVD systems can reduce a 90% consolidation time from 42 years to 12 months.
Standard penetration test (spt)
The standard penetration test (SPT) involves driving a split spoon sampler into the ground using a 140 lb hammer dropped 30 inches. The number of blows required to penetrate each 6 inch interval is recorded, and the penetration resistance value N is the sum of the blows over the second and third intervals. This test is commonly used to obtain bearing capacity and estimate soil properties like density and shear strength. It is performed whenever the soil stratum changes and at intervals of no more than 1.5 meters.
Excavation 2014a-Lecture3
1. The document discusses excavation work for building foundations, including determining the type and depth of excavation needed and which measurement clauses to apply.
2. Excavation work includes measuring the volume of soil removed for footings and pile caps, as well as disposing of surplus soil according to clauses for on-site or off-site removal.
3. Calculating excavation work requires identifying the foundation type from drawings, finding the relevant clause, and measuring the excavation depth, length, and width to determine the excavated material volume.

Standard Penetration Test
The document summarizes the standard penetration test (SPT), a common in situ geotechnical testing method. It describes the basic procedure, which involves driving a split spoon sampler into subsurface soils using a hammer, and recording the number of blows required for each increment of penetration. Corrections are made to SPT values to account for overburden pressure and dilatancy. Empirical correlations are presented relating SPT values to properties like density, shear strength, and consistency of cohesionless and cohesive soils. Both advantages like being inexpensive and quick, and limitations like lack of precision are discussed.
Compacting Factor Test
This document describes procedures for conducting a compacting factor test of concrete. It involves the following steps:
1. Greasing the compacting factor apparatus and weighing the empty cylinder.
2. Mixing concrete with a specific water-cement ratio and filling the upper hopper.
3. Allowing the concrete to fall into the cylinder to achieve partial compaction.
4. Filling and vibrating the cylinder in layers to achieve full compaction and weighing.
5. Calculating the compaction factor using the weights.
Plate load test
Plate load tests are used to determine the ultimate bearing capacity and settlement of soil. The test involves gradually loading a circular or square test plate placed in an excavated pit using a hydraulic jack. Dial gauges measure the settlement under each load increment. A load-settlement curve is generated, allowing engineers to determine the safe bearing capacity based on shear failure or permissible settlement. Results provide insight into foundation design and behavior for the site.
CBR TEST
The California Bearing Ratio (CBR) test measures the bearing capacity of a soil by determining the ratio of the force required to penetrate a soil mass with a standard plunger to that of a standard material. It is used to classify and evaluate soils for flexible pavement subgrades and bases. The procedure involves compacting a soil sample, soaking it for 4 days, and then applying a load through a plunger at a rate of 1.25 mm/min while measuring penetration. Load readings are recorded and used to calculate the CBR value based on standard pressures at 2.5 and 5.0 mm penetrations.

A Designer's Introduction to the Development, Design and Application of Vinyl...Docks & Marinas, Inc.
The document provides an overview of vinyl and composite sheet pile materials for use in seawalls, bulkheads, levees, and other coastal structures. It discusses the advantages of ESP's vinyl and fiber reinforced polymer (FRP) composite sheet piles over traditional materials like steel and concrete in terms of cost, weight, durability, and resistance to corrosion and rot. The document also provides details on ESP's sheet pile profiles and material properties, design and installation considerations, and examples of completed projects using ESP sheet piles worldwide.mech STONE MASTIC ASPHALT ppt
This document provides an overview of stone mastic asphalt (SMA), including its history, composition, advantages, disadvantages, and applications. SMA was developed in Germany in the 1960s to provide maximum resistance to rutting from studded tires. It has a high stone content of at least 70% that forms an interlocking skeleton structure filled with stiff bituminous mastic. SMA exhibits high resistance to rutting and wear, and increases pavement life by 20-30% over conventional pavements, making it suitable for heavily trafficked roads. However, it also has higher material and construction costs than other asphalt mixes.
Some common defects in steel structural erection at site
The document lists common defects found in steel structural erection at construction sites. These defects include a lack of grouting, poor quality high-current welding with spatters, chute liners welded instead of bolted, rusted bolts, gusset plates cut to fit bolts, misaligned holes, rusty foundation bolts, distortion of members, gaps in fitting bolts, and superstructures erected without proper alignment or grouting. The author concludes the defects demonstrate bad workmanship and pose dangers.
TYPES OF SHEAR FAILURE UNDER FOOTING
General shear failure occurs in narrow, shallow footings on dense, incompressible soils. Local shear failure features slip lines below and slightly into footings on weaker soils or wider/deeper footings. Punching shear failure results from highly compressible soils, compressing under footings without defined slip lines or lateral soil involvement.
Pipe Jacking
Pipe jacking is a trenchless construction method where pipes are pushed through the ground behind a tunneling shield using hydraulic jacks. The process involves excavating soil within the shield as it advances forward in a continuous process until the pipeline is completed. It provides a structurally sound, watertight finished pipeline and avoids excavating trenches, making it suitable for installing pipes in urban areas with existing infrastructure. Some key equipment used includes jacks, pipes, thrust rings to distribute force evenly, and cutter heads to excavate the soil.

Research in geotechnical engineering
Ground improvement involves altering the properties of soil to better suit engineering project requirements rather than changing the design. This involves reducing settlement, increasing shear strength and bearing capacity, and improving liquefaction resistance. A simple demonstration showed how adding a cloth layer to a pile of sand reduced dispersion, analogous to how geosynthetics can improve soil. Geogrids are polymer meshes that reinforce soil through friction and adhesion. Geotextiles and geogrids can reduce required pavement thickness for roads by improving soil strength properties.

Geosynthetic clay liners (GCLs) are materials used to line landfills that incorporate a layer of bentonite clay between two layers of geosynthetic fabric. The low permeability of the bentonite clay slows the rate of liquid seepage out of the landfill. GCLs are fast and easy to install, have very low hydraulic conductivity, and can self-repair tears due to the swelling properties of bentonite. They are increasingly used as barriers in mining and industrial facilities due to their ability to form a hydraulic barrier with low permeability. GCLs consist of bentonite clay bonded between one or more layers of geosynthetic material such as geotextiles or geomembranes. The

Geotextiles are permeable fabrics used with soil, rock, earth, and other geotechnical engineering related material as an interface. The document discusses the functions, classification, production process, forms, properties of fibers, and applications of geotextiles. Geotextiles are used for separation, filtration, drainage, reinforcement, protection, and erosion control in applications such as roads, railways, retaining walls, slopes, shorelines, and landfills. Common materials used include polypropylene, polyester, and natural fibers like jute. Geotextiles come in various forms like geomembranes, geogrids, geonets, and geocomposites.
Presentation on Geo textile.
The document provides information about geo textiles, including:
- Their basic functions like separation, filtration, reinforcement, and drainage.
- Common types are woven and non-woven fabrics made of polypropylene or polyester.
- They are tested to standards like ASTM to ensure strength, permeability, and resistance to puncture, tearing, and UV degradation.
- Proper installation requires sewing machines, thread, and a three-person team to accurately place and stitch the geo textile materials.
Hydroplast - Flawless waterproofing
Engineering structure decks are made of carefully formulated concrete but nevertheless
require surface waterproofing to protect their reinforcing or prestressing steel from corrosion.
Polymer bitumen membranes can be used to ensure durable waterproofing, even when the
concrete is cracked. Eurovia’s Hydroplast® sheet is a high-performance solution.

Explore Amazing Features Of Woven Geotextile
Woven geotextile is a strong, durable fabric made from polypropylene film that is slit into tapes and yarns, then woven into a uniform structure up to 17.5 feet wide. It is ideal for separation, soil reinforcement, ground reinforcement, and filtration due to its high tensile strength, water permeability that is higher than most soils, and controlled opening size that prevents clogging. The geotextile delivers outstanding water flow and filtration performance for drainage, river defense, sports surfaces, and equestrian areas.
Grouting various techniques of grouting.pptx
Grouting involves injecting a slurry or liquid into soil or rock to fill voids and fractures. There are three main modes of grouting: permeation where grout freely flows into voids, compaction where grout remains intact and exerts pressure, and hydraulic fracturing where grout rapidly penetrates fractured zones. Common grout materials include suspensions of cement and water, emulsions of asphalt and water, and chemical solutions. Important grout properties include viscosity, setting time, strength, stability, and toxicity. Common grouting methods are permeation, compaction, jet, and soil fracture grouting. Grouting is used for applications such as seepage control, soil stabilization, vibration control,

Performance of geosynthetic filters in treatment of urban storm water runoff
This document discusses the performance of geosynthetic filters in treating urban stormwater runoff. It begins with an introduction to urban stormwater issues and current treatment methods. It then provides details on geosynthetic filters, including the types of geotextiles, manufacturing processes, and design requirements. The document finds that geotextiles can effectively remove suspended solids from stormwater runoff while requiring less maintenance than other filtration methods. It proposes new design criteria for selecting geotextiles based on ratios of pore and particle sizes. The conclusion is that nonwoven polypropylene geotextiles with smaller opening sizes, permittivities and porosities are most suitable for urban stormwater filtration.
