Program
I - Compressibility and consolidation of clay layers: stress-strain in soils under confinement conditions, weather effects, different types of clayey soils, edometric testing and determination of parameters for calculation of settlements and consolidation. Terzaghi Consolidation Theory. Two-dimensional and three-dimensional consolidation. Biot theory. Terzaghi Theory solutions for any distributions of the initial neutral pressure excesses. Secondary consolidation. Accelerating consolidation. 2 - Shear strength: Tresca and Mohr-Coulomb failure criteria, tests to determine the shear strength in laboratory, Mohr-Coulomb envelope based on the test results. Shear strength and stress-strain relationships in sands and clays. Neutral pressure parameters.3 - Earth impulses. 4-Stability of slopes in rock and soil. Methods for calculation. Techniques for stabilization. 5- Geotechnical investigation and testing. 6- Monitoring. 7- Eurocode 7. Exercise resolution. Exercise resolution.
Evaluation Methodology
The assessment consists of a written test, at the different assessment periods, including theoretical and practical components. Pass requirements: a mark of at least 40% in each component and a minimum global mark of 9.5 in 20.
