Infrastrutures and other works
Objectives
Learning fundamental concepts related to geotechnical works of railways, highways, waste landfills and foundation of buildings, bridges and related structures, particularly regarding the management of geotechnical studies, geotechnical modeling of ground behaviour, types of treatments frequently used, construction methods and technical support on site.

Teaching method
The teaching, supported in the use of multimedia projections and e-learning methods (Moodle program), embrace theoretical and practical lessons, namely with critical review of geotechnical projects and the execution of site investigation plans and geotechnical zoning, complemented by seminaries (at least four) with specialists on the geotechnical works addressed.
The evaluation will have a continuous component and includes two tests - T (practical and theoretical) and an individual work (W), a thematic study on a subject taught. Final grade: 0,8.(T1+T2) + 0, 2.(W) = 20 values
Evaluation method
The evaluation will have a continuous component and includes two tests - T (practical and theoretical) and an individual work tasl (W) on a thematic study on a subject taught.
Final grade: 0,8.(T1+T2) + 0, 2.(W) = 20 values
The frequency will be guaranteed in the case of a positive grade on the work task. The frequency of this unit will be valid for the corresponding academic year. In case of failure of approving at the written tests/exam, it will be valid too for the following academic year.
