Recommended Prerequisites

 Knowledge of  Engineering Geology and Soil Mechanics. 

Teaching Methods

Lectures with exposure of the subject to be taught.
- Classes for silving problems involving the earthworks and soil compaction.
- Visits to ongoing works which were designed / applied techniques in order to improve the characteristics of soil/rocks/rock masses (slopes and underground works) and foundation (dams, consolidation and waterproofing curtains).

Learning Outcomes

Each student should carry out  detailed knowledge about:
- Design and construction of earthworks;
- Improving the characteristics of the soils and rocks/rock masses.
