Knowledge

Student will master the course objective and will have basic knowledge about soil properties and soil behaviour for safe and economical design of foundations, design of earth body and for vertical structures design.

Syllabus

1. Introduction to soil mechanics (basic characteristics of soils; origin, formation, mineralogy, grain size composition).
2. Index and state properties of soils. Classification of soils for engineering purposes.
3. Basic of geomechanics – (Stress and strain in soil; Mohr´s circle; Principle of effective stress, The mechanical behavior of materials - elasticity, plasticity, failure; drainaed, undrained conditions; the effect of time).
4. Importance of water in soil (permeability, steady state seepage).
5. Compressibility of soil (isotropic, One-dimensional, over-consolidation).
