Educational objectives Comprehension of basic concept and principles of soil mechanics. Knowledge of main methods used in professional practice for design of spread foundations, piled foundations and retaining structures.
Prerequisites It is necessary to pass the exam of Scienza delle costruzioni (Mechanics of materrials). Some basic knowledge of Hydraulics are also necessary, such as : hydraulic head, Bernoulli's law, laminar flow.
Teaching methods Lessons (by using blackboard and overhead projector).
Other information 1) About 20 hours of tutorship in class.
2) Guided visit to the Geotechnical laboratory.
Learning verification modality One written exam (about three hours) followed by an oral exam.
