It is a specialized course that discusses the properties and mechanical behavior of geo-materials, soils and rocks, aiming to the geo-technical assessment of the subsoil and the safe design of engineering projects.
PHYSICAL CHARACTERISTICS OF THE SOIL (Origin and nature of soil, Phase diagram, Physical properties of soils, relative density , Particle size analysis, Classification of soils, Compaction); STRESS AND STRAIN (Definition of stress and strain, Geostatic stress, Effective stress principle); SHEAR STRENGTH OF SOILS (Mohr’s circle representation of stresses, Stress –strain relationships at failure, Direct shear test, Triaxial test); STRESS-STRAIN RELATIONS OF SOIL MATERIALS (Linear isotropic elasticity, Non-linear stress-strain relations, Compressibility: consolidation settlement, time rate consolidation- consolidation test); MECHANICAL BEHAVIOR OF INTACT ROCK (Rock strength, Elastic properties, Uniaxial compression test, Point load strength index, Tensile strength, Shear strength (Mohr-Coulomb and Hoek and Brown failure criterions); MECHANICAL BEHAVIOR OF ROCKMASS (Rock mass discontinuities: geometrical and mechanical characteristics and their influence on the behavior of the rock mass, Shear strength of discontinuities).
