The course of Geotechnics I aims to provide students with the basic knowledge of the mechanical and hydraulic behaviour of soils and the theoretical foundations of the main methods used in engineering practice, for the design and verification of foundation structures and earth-supporting works.
Geotechnics I is a teaching characterizing the Degree Course in Civil Engineering that aims to form a professional profile of civil engineer mainly oriented to the fields of hydraulic engineering, engineering of structures and road infrastructure and, more generally, transport systems. This engineer profile will be able to carry out design, construction, management, control and maintenance of all civil works.
The course will cover the basic topics of soil mechanics, such as: type and constitution of soils, their multiphase nature, the principle of effective stresses, the seepage flow and experimental tests for the determination of physical and mechanical parameters. In addition, knowledge will be provided of some analytical methods for calculating the thrust of soil on the support structures and for calculating the limit load and subsidence of surface foundations.
At the end of the course students will be able to interpret the main laboratory geotechnical tests, perform basic geotechnical calculations for the dimensioning of support walls and shallow foundations, assess the
