Foundation Engineering
Code – CE- 703
Site Investigation & Soil Exploration: Planning of sub-surface exploration , methods , sampling, samples, Insitu tests:
SPT, SCPT, DCPT, field vane shear , Plate load test, Bore log, preparation of sub-soil Investigation report .
Foundations: Classification, selection- shallow and deep foundations.
Shallow foundations : Bearing capacity, Terzaghi’s bearing capacity theory, effect of depth of embedment, eccentricity of load, foundation shape on bearing capacity , Bearing capacity on layered media, Bearing
capacity as per 1S 6403.
Settlement: Immediate and consolidation settlement , correction for rigidity and dimensional effects, settlement in various types of soil , IS-1904 recommendations.
Allowable bearing capacity: Definition, Determination of allowable bearing capacity from insitu test- SPT , SCPT and Plate load test.
Deep foundations: Pile: Types, load transfer mechanism , method of installation of piles- classification base on material , Installation Techniques – Selection and uses, Determination of load carrying capacities of piles by static and Dynamic formulae, Pile group .
