Learning Outcomes : Upon successful completion of the course, the student will be able to: • Distinguish soils into two main categories (sands and clays), according to their physical characteristics and mechanical properties. • Understand the mechanical behavior and response of soils in the context of designing and constructing technical projects and recognize the appropriate data for performing geotechnical tests. • Understand and distinguish concepts such as shear strength – compressibility, effective – total stresses, cohesive (fine-grained) – non-cohesive (coarse-grained) soils, undrained – drained loading conditions, immediate settlements – consolidation settlements. • Calculate stresses and pore pressures in the soil, both due to self-weight and due to applied loads. • Understand basic concepts of flow and permeability in soils.
