Introduction to the course

1. Characteristics of soils
• origin of natural soils, marine and continental environment
• identification and classification of soils

2. Porous continuous medium model
• review on stress analysis, Mohr circle
• review on strain analysis, volume change and distortion
• principle of effective stresses
• equations of equilibrium and compatibility

3. Distribution of pore pressures and stress in the soil
• hydrostatic conditions, capillary rise
• filtration motions (1D only) in soils
• tests for permeability measurement
• lithostatic stress state

4. Models of elastic and plastic material
• linear elasticity; drained and not drained conditions; ideal sampling
• elements of plasticity theory (1D conditions only)
• viscosity

5. Compressibility of soils
• mechanical laboratory tests
• edometric compression test
• analysis of the consolidation process

6. Deformability and resistance of soils
