Fundations and Retaining Works

Recommended Prerequisites

Engineering Geology (LEC)

Soil Mechanics (LEC)

Stability of Geotechnical Structures (LEC)

Geotechnical Works (MEC).

Teaching Methods

Teaching model based on theoretical-practical classes, combining in a balanced way theoretical explanations of concepts and theories related to the topics with the presentation and discussion of case studies, and also contact with relevant projects, either through invited experts either through visits to construction sites.

Students will also be encouraged to make small practical course works in order to implement the knowledge acquired, simulating simplified real cases. Final exam foccused on theoretical matters and on the conception of solutions.

Learning Outcomes

With this unit it is intended that the student acquires relevant expertise and tools, allowing to take technical decisions, duly justified in the context of design, construction and monitoring during construction of various types of fundations and retaining works. At the end of the course the student should be able to:

- Understand the phenomenology and behavior of an excavation work;

- Select the adequated constructive solutions;

- Identify the methods of analysis and design;

- Develop analytical and numerical models to calculate a flexible earth retaining structure or a tunnel;

- Plan observation campaings

- Evaluate the risks associated and design and implement mitigation measures.
