Geotechnics II aims at providing knowledge and competences for the proper definition of geotechnical models, for the planning of sampling and testing campaigns, both in situ and in laboratory, for the design of foundations of civil infrastructures and structures.
At the end of the course students shall be able of 1) selecting the appropriate sampling and testing techniques; 2) providing a correct interpretation of the available data and defining a geotechnical model of the soil, to develop the design of foundations; 3) carrying out analyses aimed at the predicting the operational behaviour and the potential failure modes of the most common geotechnical structures; 4) preparing a report that clearly illustrates the models and the results of the analyses.
