rotatory drilling – Depth of boring – Spacing of bore hole - Sampling – Representative
and undisturbed sampling – Sampling techniques – Split spoon sampler, thin tube
sampler, stationary piston sampler – Bore log report – Penetration tests (SPT and SCPT)
– Data interpretation (Strength parameters and Liquefaction potential) – Selection of
foundation based on soil condition.
UNIT II SHALLOW FOUNDATION 9
Introduction–Location and depth of foundation – Codal provisions – Bearing capacity of
shallow foundation on homogeneous deposits – Terzaghi’s formula and BIS formula –
Factors affecting bearing capacity – Problems-bearing Capacity from insitu tests (SPT,
SCPT and plate load) – Allowable bearing pressure, settlement – Components of
settlement – Determination of settlement of foundations on granular and clay deposits –
Allowable settlements – Codal provision – Methods of minimizing settlement –
Differential settlement.
UNIT III FOOTINGS AND RAFTS 9
Types of foundation – Contact pressure distribution below footings and raft – Isolated
and combined footings – Types – Proportioning – Mat foundation – Types – Use –
Proportioning – Floating foundation.
UNIT IV PILES 9
Types of piles and their function – Factors influencing the selection of pile – Carrying
capacity of single pile in granular and cohesive soil – Static formula – Dynamic formulae
(Engineering news and Hiley’s) – Capacity from insitu tests (SPT and SCPT) – Negative
skin friction – Uplift capacity – Group capacity by different methods (Feld’s rule,
Converse Labarra formula and block failure criterion) – Settlement of pile groups –
Interpretation of pile load test – Forces on pile caps – Under reamed piles – Capacity
under compression and uplift.
UNIT V RETAINING WALLS 9
Plastic equilibrium in soils – Active and passive states – Rankine’s theory – Cohesionless
and cohesive soil – Coloumb’s wedge theory – Condition for critical failure plane –
Earth pressure on retaining walls of simple configurations – Graphical methods (Rebhann
and Culmann) – Pressure on the wall due to line load – Stability of retaining walls.
