Learning outcomes of the course unit
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.
