Geotechnics

Being the first course unit in Geotechnics and foundations, no specific requirements are needed. Only basic knowledge in mathematics and physics is needed.

In Theoretical-Practical lessons the expository and inquisitive method is used during the explanation of the theoretical subjects and exercises are solved in groups and individually. Students should perform in groups two practical assignments with treatment and technical interpretation on results of laboratory tests and another two assignments should be individually solved in laboratorial class. In Tutorial classes students will be supervised, through the clarification of theoretical doubts, exercises resolution and guidance of the practical assignments. Field trips will be held whenever possible. 

Learning objectives: knowledge of different types of rocks and soils. To carry out basic soil tests. Knowledge of main methods of in-situ investigations.
Generic skills: Ability for acquisition and application of knowledge and for solving problems. Ability for individual work and for working in groups.
Specific skills: To know theoretical and practical concepts in Geotechnics, Soil Mechanics and Rock Mechanics and using them in solution of problems on structures and geothecnical works.
