Precautions like maintaining verticality and limiting tilt and shift are important during well sinking.
The document discusses foundation treatment and galleries in concrete gravity dams. Foundation treatment involves preparing the surface by excavating loose soil till bedrock and stepping the surface. It also involves consolidation grouting of the entire foundation before concreting and curtain grouting near the heel after some concreting. Galleries are horizontal or sloping passages in the dam body used for drainage, inspection, aeration, pipe installation, and foundation drilling/grouting. Common gallery types include foundation, inspection, and aeration galleries. Reinforcement is provided at gallery corners to reduce stress concentrations.
This document discusses theories for designing weirs on permeable foundations to prevent failures from seepage. It describes Bligh's creep theory, Lane's weighted creep theory, and Khosla's theory. Bligh's theory calculates creep length and floor thickness but does not distinguish horizontal from vertical creep. Lane's theory assigns higher weight to vertical creep. Khosla's theory accounts for pressure distributions and recommends cut-offs and aprons. It is commonly used but requires corrections for floor thickness, pile interference, and slope. Inverted filters and launching aprons are also discussed.
A weir is a solid structure built across a river to raise the water level and divert water into canals. There are different types of weirs including masonry weirs with vertical drops, rock fill weirs with sloping aprons, and concrete weirs with downstream slopes. Weirs can fail due to subsurface piping, uplift pressure, surface water suction or scouring. Remedies include installing sheet piles and ensuring sufficient floor thickness and length. A barrage is similar to a weir but uses gates rather than a solid structure to control water levels. Barrages are more expensive than weirs but allow better control of water levels and less silting during floods by raising the gates.
Dams are constructed across rivers to store water in reservoirs. There are several types of dams classified based on their use, hydraulic design, materials used, and mode of stability. The key types include storage dams, diversion dams, detention dams, gravity dams, buttress dams, arch dams, earth dams, and rockfill dams. Dams require site selection studies involving foundation conditions, material availability, and reservoir capacity. Investigation of dam sites includes surveys and testing. Reservoirs have storage zones and evaporation losses need to be estimated. Spillways like chute spillways, shaft spillways, and tunnel spillways are constructed for surplus discharge. Earth dams are economical but require suitable foundations and can fail due to seep
Vibration method for ground improvement techniqueABHISHEK THAKKAE
This document discusses various ground improvement techniques, including vertical drains, soil nailing, stone columns, vibro compaction, and dynamic compaction. Vertical drains accelerate consolidation by facilitating drainage of pore water through columns of pervious material placed in soil. Soil nailing uses steel tendons drilled and grouted into soil to create a reinforced composite mass. Stone columns form vertical columns of compacted aggregate through problem soils to increase strength and reduce compressibility. Vibro compaction densifies loose sands using vibratory probes to achieve a denser soil structure. Dynamic compaction improves soil by repeatedly dropping heavy weights onto the ground from heights of 40 to 80 feet.
The document discusses and compares the theories of Kennedy and Lacey regarding stable channel design for irrigation canals. Kennedy's theory is based on the concept of critical velocity to prevent silting, while Lacey's regime theory differentiates between true, initial, and final regimes and introduces the concept of a silt factor. The key differences between the two theories are also summarized.
Field control of compaction and compaction Equipmentaishgup
This document discusses field compaction control and compaction equipment. It notes that field compaction depends on placement water content, compaction equipment type, and soil type. Placement water content should be within 2% of optimum moisture content from lab tests. Different soils require different moisture levels - cohesive soils are compacted dry of optimum while earth dam cores are compacted wet of optimum. Compaction can be measured using methods like core cutting or nuclear gauges. Common compaction equipment includes smooth drum rollers, pneumatic rubber-tired rollers, sheepfoot rollers, and vibratory rollers, each suited to different soil types. Relative compaction is used to check compaction levels in the field.
This document discusses various ground improvement techniques used to address problematic soils and ground conditions. It covers methods like compaction, dynamic compaction, vibro-displacement, preloading with vertical drains, deep soil mixing, grouting, ground freezing, biotechnical stabilization, reinforced soil, and geosynthetics reinforcement. The selection of a technique depends on factors like the type of ground, required improvement, constraints, and costs. Proper design, execution, and quality control are needed to effectively apply these ground improvement methods.
This document discusses different types of canal falls, which are structures constructed to lower the bed level of a canal. It describes seven common types of falls: ogee fall, rapid fall, trapezoidal fall, stepped fall, montague fall, vertical drop fall, and straight glacis fall. Each type is suitable for different conditions depending on factors like the height of fall, discharge, site topography, and cost. The document provides details on the design and suitability of each type of canal fall.
Spillways are structures used to safely discharge water from a reservoir during periods of high inflow or flooding. They are designed to maintain structural stability of the dam and pass excess water without raising the reservoir level above its maximum. Different types of spillways include overflow, chute, shaft, saddle and side channel spillways. Energy dissipation methods are also important to safely convey water discharged from spillways downstream.
This document discusses different types of canal lining materials and their advantages. It states that lining canals reduces water losses through seepage and prevents waterlogging of adjacent lands. It allows for smaller canal dimensions since lined canals have lower resistance to flow. Lining also reduces maintenance needs like silt removal and bank repairs. Common lining materials described include cement concrete, shotcrete, precast concrete, brick and various earth linings. Cement concrete lining provides excellent hydraulic properties but has high costs. Shotcrete and cement mortar linings use large amounts of cement. Brick lining allows for easy repair and is hydraulically efficient. Lining improves water conservation and irrigation capacity but requires heavy initial investment.
Spillway crest gates are adjustable gates used to control water flow in reservoir and river systems. They act as barriers to store additional water, allowing the height of dams to be increased and requiring more land acquisition. The main types of spillway gates are dripping shutters, stop logs, radial/tainter gates, drum gates, and vertical lift/rectangle gates. Vertical lift gates are rectangular gates that spin horizontally between grooved piers and can be raised or lowered by a hoisting mechanism to control water flow.
This document discusses various types of canal regulation works including canal falls, escapes, regulators, and outlets. It describes the necessity and types of canal falls, which are constructed when the natural ground slope is steeper than the designed canal bed slope. The types of falls discussed include ogee falls, stepped falls, vertical falls, rapid falls, straight glacis falls, trapezoidal notch falls, well or cylinder notch falls, Montague type falls, and Inglis or baffle falls. The document also discusses canal escapes, head regulators, cross regulators, silt control devices, and canal outlets/modules. In particular, it explains the functions and construction of head regulators and cross regulators.
The presentation illustrates a technique for ground improvement, Grouting. In India, grouting is still not being used very much. In this presentation, I have demonstrated the basic types of grouting, goals of ground improvement and two case studies of grouting.

Cross drainage works (CDWs) are structures constructed where canals intersect natural drainages like rivers or streams. There are three main types of CDWs depending on the relative bed levels: 1) aqueducts or siphon aqueducts where the canal passes over the drainage, 2) super passages or siphon super passages where the drainage passes over the canal, and 3) level crossings where the canal and drainage intersect at the same level. The appropriate type of CDW is selected based on factors like relative bed levels, availability of suitable foundation, economic considerations, and discharge of the drainage. Key steps in planning CDWs include selecting a suitable site where the drainage crosses the canal alignment at a right angle and on

Dewatering is the process of removing water from construction sites to allow excavation work to be done safely and efficiently below the water table. There are several reasons why dewatering is needed, including providing a dry work area, improving stability, and increasing safety. Common dewatering techniques include sump pumping, well points, deep wells, and trenches. Each method has advantages and disadvantages depending on the site conditions and depth of water lowering required. Proper planning and design of a dewatering system is important to effectively control groundwater and allow construction work to progress smoothly.

An improved modulation technique suitable for a three level flying capacitor ...IJECEIAES
This research paper introduces an innovative modulation technique for controlling a 3-level flying capacitor multilevel inverter (FCMLI), aiming to streamline the modulation process in contrast to conventional methods. The proposed
simplified modulation technique paves the way for more straightforward and
efficient control of multilevel inverters, enabling their widespread adoption and
integration into modern power electronic systems. Through the amalgamation of
sinusoidal pulse width modulation (SPWM) with a high-frequency square wave
pulse, this controlling technique attains energy equilibrium across the coupling
capacitor. The modulation scheme incorporates a simplified switching pattern
and a decreased count of voltage references, thereby simplifying the control
algorithm.

Advanced control scheme of doubly fed induction generator for wind turbine us...IJECEIAES
This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
