Elective
2nd Cycle Studies - Mestrado
Recommended Prerequisites
Engineering Geology (LEC)
Soil Mechanics (LEC)
Stability of Geotechnical Structures (LEC)
Geotechnical Works (MEC).
Teaching Methods
Practical-theoretical lectures
1. Use a audiovisuals means to explain the main theories and principals of the subjects.
2. Resolution of problems. Use of Plaxis and Slide codes to solve geotechnical problems
3. Laboratory lectures, demonstration of testing equipments and visit to works.
Learning Outcomes
To provide advanced formation in terms of conception, design, construction and observation of geotechnical works, namely when the execution of embankments has an important role (p.e, embankments for roads, earth dams, etc).
Acquiring capabilities in synthesis and analysis, oral and written communication, computer skills related with the issues studied, problems solving, critic reflection, autonomous learning and practical application of theoretical knowledge.
Work Placement(s)
NoSyllabus
1. Embankments – general
