The main goals of the course are:
- to provide basic knowledge of soil mechanics, soil hydraulics, stress-strain laws, in situ and laboratory tests (D1. Knowledge and understanding);
- to apply the acquired knowledge for designing and verifying the most common earth works (shallow and deep foundations, embankments and excavations, retaining walls, etc.);(D2. Applying knowledge and understanding; D3. Making judgements; D5. Learning skills)
- to learn how to use of the most correct and appropriate terminology of the discipline.

*an e-mail of request from the student as well as the confirmation by the lecturer are needed in both cases

Written and oral tests are requested to verify if the students
- have acquired the basic knowledge of soil mechanics, soil hydraulics, stress-strain laws, in situ and laboratory tests (D1. Knowledge and understanding; D5. Learning skills);
- are able to apply the acquired knowledge for designing and verifying the most common earth works (shallow and deep foundations, embankments and excavations, retaining walls, etc.) (D2. Applying knowledge and understanding; D3. Making judgements)
- have learnt to use of the most correct and appropriate terminology of the discipline.(D4. Communication skills)
