Gaining knowledge about the behavior of soils, their classification and description, the influence of water on the behavior of soil, laboratory testing of soils. Solving basic geotechnical problems using analytical methods (settlement and bearing capacity of the base surface, slope stability, earth pressure).

Completing the course the student will get knowledge about soil behavior under various loading conditions. Will be able to evaluate the deformation and strength characteristics of soils. It will focus on laboratory tests that need to be selected for characterization of soils. Application of soil properties for foundation design surface, slope stability assessment and determination of earth pressures.

Knowledge from Geology (soil formation, types of foundation soils). Fundamentals of Structural mechanics.

Elasticity and Plasticity

The presented topic is practiced on credit examples including the parts individually discussed. Part of the exercise takes place in soil mechanics laboratory.
Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations.

Conditions of credit is to develope a final credit examples and laboratory reports and satisfying attendance.The exam will consist of written ((in the form of brief answers to questions such as including sketching graphs, a simple calculation) and oral part. Condition of the oral exam is a written test conditions.

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).
6. Consolidation; Creep (theory + laboratory testing); settlement (immediate, consolidation and total).
7. Shear strength of soils (peak, critical, residual).
8. Shear strength of soils continuation.
