Learning outcomes |
In this UC is intended that the student learn concepts, theories and principles required to solve elementary geotechnical problems, to give reasons for its proposals, and skills in compaction control and prediction of the hydraulic and mechanical behaviour of natural or earthfill massifs under loadings. At the end of the UC the student should be able to:
- define, identify and classify soils
- distinguish soil types taking into account their physical and identification characteristics
- understand the principle of soil compaction and their application
- characterize the soil’s state in different geotechnical situations
- understand the concept of stress in soil masses, at equilibrium or subject to seepage
- calculate the stress state at-rest and after ground surface loading
- evaluate the permeability coefficient and formulate seepage problems
- identify emerging geomaterials
- determine from experimental tests: physical and identification characteristics, compaction and permeability

Teaching Methodologies and Assessment Criteria |
This one semester Course Unit involves 60 hours of scheduled contact activities, taught teaching-learning sessions, organised in theoretical classes (30 T: presentation of syllabus, with reference to elementary geotechnical problems that foster the practical interest of the subject), theoretical-practical classes (15 TP: resolution of practical exercises from the proposed problem sheets) and laboratory practice classes (15 PL: conducting laboratory tests with further treatment and interpretation of experimental data).
In the evaluation are considered written tests (E) and laboratory work with report writing (TR). The classification (CF) is awarded according to the following requirements:
CF = max (0.2 x TR + 0.8 x E) with TR > 9.5 v. and E > 9.5 v. Oral examination if CF > 16.5 v.
