CE8491 Soil Mechanics Syllabus:

CE8491 Soil Mechanics Syllabus – Anna University Regulation 2017

OBJECTIVES:

• To impart knowledge to classify the soil based on index properties and to assess their engineering properties based on the classification. To familiarize the students about the fundamental concepts of compaction, flow through soil, stress transformation, stress distribution, consolidation and shear strength of soils. To impart knowledge of design of both finite and infinite slopes.

UNIT I SOIL CLASSIFICATION AND COMPACTION

History — formation and types of soil — composition — Index properties — clay mineralogy structural arrangement of grains — description — Classification — BIS — US — phase relationship — Compaction — theory — laboratory and field technology — field Compaction method — factors influencing compaction.

UNIT II EFFECTIVE STRESS AND PERMEABILITY

Soil — water — Static pressure in water — Effective stress concepts in soils — Capillary phenomena–
— Permeability — Darcy?s law — Determination of Permeability — Laboratory Determination (Constant head and falling head methods) and field measurement pumping out in unconfined and confined aquifer — Factors influencing permeability of soils — Seepage — Two dimensional flow — Laplace?s equation — Introduction to flow nets — Simple problems Sheet pile and wier.

UNIT III STRESS DISTRIBUTION AND SETTLEMENT

Stress distribution in homogeneous and isotropic medium — Boussines of theory — (Point load, Line load and udl) Use of Newmarks influence chart –Components of settlement — Immediate and consolidation settlement — Factors influencing settlement — Terzaghi?s one dimensional consolidation theory — Computation of rate of settlement. — vt and log t methods. e-log p relationship consolidation settlement N-C clays — O.C clays — Computation.

UNIT IV SHEAR STRENGTH

Shear strength of cohesive and cohesion less soils — Mohr-Coulomb failure theory — shear strength — Direct shear, Triaxial compression, UCC and Vane shear tests — Pore pressure parameters — Factors influences shear strength of soil.

UNIT V SLOPE STABILITY

Infinite slopes and finite slopes —- Friction circle method — Use of stability number –Guidelines for location of critical slope surface in cohesive and c — soil — Slope protection measures.
