Drainage and Dewatering methods, estimation of the depth of GWT (Hvorslev’s method). 


Stress in Soils: Introduction, Boussinesq’s and Westergaard’s theory concentrated load, circular and rectangular load, equivalent point load method, pressure distribution diagrams and contact pressure, Newmark’s chart.
Foundation Settlement: Types of settlements and importance, Computation of immediate and consolidation settlement, permissible differential and total settlements (IS 8009 part 1)


Lateral Earth Pressure: Active, Passive and earth pressure at rest, Rankine’s theory for cohesionless and cohesive soils, Coulomb’s theory, Rebhann’s and Culmann’s graphical construction.
Stability of Slopes: Assumptions, infinite and finite slopes, a factor of safety, Swedish slip circle method for C and C-ø (Method of slices) soils, Fellineous method for critical slip circle, use of Taylor’s stability charts.

Effect of the water table and/or eccentricity on bearing capacity of the soil, field methods of determining the bearing capacity of soil: SPT and plate load test. 


Pile Foundations: Types and classification of piles, single loaded pile capacity in cohesionless and cohesive soils by static and Dynamic formulas, the efficiency of Pile group, group capacity of piles in cohesionless and cohesive soils, negative skin friction, pile load tests, Settlement of piles, under reamed piles (only introductory concepts – no derivation).
