OBJECTIVE:
To impart knowledge on behaviour and the performance of saturated soil. At the end of this
course student attains adequate knowledge in assessing both Physical and Engineering
behaviour of soils, mechanism of stress transfer in two-phase systems and stability analysis of
slope.
UNIT I SOIL CLASSIFICATION AND COMPACTION 9
Nature of soil – phase relationships – Soil description and classification for engineering
purposes, their significance – BIS Classification system – Soil compaction – Theory,
comparison of laboratory and field compaction methods – Factors influencing compaction
behaviour of soils.
UNIT II SOIL WATER AND WATER FLOW 7
Soil water – static pressure in water – capillary stress – Permeability measurement in the
laboratory and field – pumping in and pumping out tests – factors influencing permeability of
soils – Seepage – introduction to flow net – Simple problems (sheet pile and wier).
UNIT III STRESS DISTRIBUTION AND SETTLEMENT 11
Effective stress concepts in soils – Stress distribution in soil media – Boussinesq theory - Use
of Newmarks influence chart – Components of settlement –– immediate and consolidation
settlement – Terzaghi’s one dimensional consolidation theory – computation of rate of
settlement- t and log t methods - Factors influencing settlement characteristics of soils.
UNIT IV SHEAR STRENGTH 9
Shear strength of cohesive and cohesionless soils – Mohr – Coulomb failure theory –
Measurement of shear strength, direct shear – Triaxial compression, UCC and Vane shear
tests – Cyclic loading – Pore pressure parameters.
UNIT V SLOPE STABILITY 9
Slope failure mechanisms – Types of slopes and infinite slopes – finite slopes – Total stress
analysis for saturated clay – Fellenius method - Friction circle method – Use of stability
number - slope protection measures.
TOTAL: 45 PERIODS
