Foundations I

Soil Mechanics.

In TP lessons an expository and inquisitive method is used for explanation of theoretical subjects and there will be individual and group resolution of exercises. Students should perform a research team work with a written report and an oral presentation. In OT classes the methodology is based on skills. The students are supervised, through the clarification of doubts, problems resolution and guidance of research tasks. Field visits will be held when possible. In Laboratory Practice classes the students watch in situ tests demonstrations and perform, present and publically defend the research group tasks.

The goals of the unit are the technology and design of earth supporting structures and foundations.
Generic skills: application of knowledge and understanding; Realization of judgment and decision making; Self-learning; Teamwork; Oral and written communication..
Specific skills: Analyze and understand the functioning of foundations and earth support structures. Recognize, diagnose and prevent geotechnical and structural pathologies in constructions, on what concerns foundations and soils support. In the case of rigid walls and shallow foundations, students will have the skills to designing, supervision, management and repair of works.
