014409 – Geomechanics

Course Objectives

The course is an integration of strength of materials and building materials, analytical description of empirical
observation. The idea of the course is to transfer the rules of soil response/behavior into analytical form. The course is divided roughly into three parts: (i) Indicative properties of soils, classification of soils, flow in saturated soils, effectives stress. (ii) Stress distribution below foundations, compressibility of soils, consolidation theory, determination of settlements. (iii) Strength of soils.
