AIMS AND LEARNING OUTCOMES

AIMS - Module 1

The objective of the module is to illustrate the fundamentals of geotechnical engineering, with particular emphasis on the physical-mechanical characterization of soils and the interaction between liquid and solid phases in porous media. The aim is therefore to introduce the main theoretical approaches for studying the hydro-mechanical response of soils and to provide the knowledge base for the subsequent engineering analyses.

LEARNING OUTCOMES: Classification of soils. Evaluation of initial stress states and their evolution over time. Analysis of seepage through porous media. One-dimensional consolidation. Soil strength for geotechnical design: modelling methods and their applicability.

TEACHING METHODS

The course consists of lectures, exercises and case studies.
