This course introduces basic concepts of geotechnical design of shallow and deep foundations including spread footings, mats and retaining walls, braced cuts and driven piles. Coverage includes bearing capacity, settlement, lateral earth pressure and group effects of the various foundation types. 

Soil Mechanics Laboratory is a laboratory works that involve in laboratory testing for soil description and classification, soil compaction, permeability and seepage through soil, shear strength of soil and consolidation of soil. smile

The objective of this course is to gain some knowledge on soil testing which is an important step in overall construction design project. The students will have opportunity to gain practical experience with some laboratory tests and methods used in soil mechanics today. The students will also gain experienced in both performance of soil tests and the subsequent analysis of that data for some of the more fundamental soil mechanics laboratory procedure.

Origins and composition of soil. Classification of soils for engineering purposes. Basic physical properties of soils. Groundwater, pore pressure and effective stress. Soil permeability and seepage: coefficient of permeability, seepage velocity and seepage pressure, constant head and falling head tests, field permeability tests, two dimensional flow, flow net, seepage through earth dam and embankments, seepage in anisotropic soils, instability due to seepage and dewatering excavations. Measurement of shear strength: shear strength and friction model, shear box test, triaxial compression test, variations in undrained strength, sensitivity of clays, pore pressure coefficients A and B, shear vane test and estimates of shear strength parameters from index tests. Consolidation theory: oedometer test, void ratio-pressure plots, normally consolidated and overconsolidated clays. Site investigation and in-situ testing. Laboratory and field testing of soils.
