Aims :

The course is intended primarily to give basic preparation in geotechnical engineering, by fundamentals of soil mechanics and soil behaviour, for the design of foundations and retaining walls.

Topics :

Basic characteristics and classification of soils. The principle of effective stress. Fundamentals of continuum mechanics. State of stress within a linear elastic half-space for different loaded areas.
Steady flow through soil. Darcy’s law. Coefficient of permeability. Seepage force and critical hydraulic gradient. Piping. General hydrodynamic equation, Laplace’s equation and its solutions.
Consolidation process. One-dimensional consolidation theory. Oedometer test. Compressibility and stress history. Preconsolidation pressure and overconsolidation ratio. Secondary compression.
Stress-strain and strength characteristics. Lab soil testing (direct shear test, triaxial tests). Mechanical behaviour of sands and of clays. Shear strength parameters.
Stability problems. Limit equilibrium method. Active and passive pressure. Earth retaining walls.
Bearing capacity of shallow and deep foundations. Settlements of shallow foundations on clayey and sandy soils.
