Foundations

Objectives

The student should be able to:

1.obtain the solutions associated to the determination of the collapse loads of the geotechnical problems studied: determination of earth pressures, bearing capacity of shallow foundations and stability of soil masses

in slopes, using limit analysis and limit equilibrium methods;

2.determine the collapse loads associated to those problems;

3.identify the ultimate limit states associated to the main geotechnical structures: retaining structures, shallow foundations and slopes;

4.verify the safety of the main geotechnical structures;

5.determine settlements of the shallow foundations.

Teaching method

Theoretical classes for presentation and explanation of the contents of the programme. Practical classes for application of the concepts learned in the theoretical classes and for use, in one of the classes, of simple model towards the understanding of the mechanisms involved in the collapse of the most simple cases studied in the unit

Evaluation method

Two tests during the semestre or final exam.

Subject matter

1.Introduction to the geotechnical structures.

2.Introduction to the collapse of soil masses. Methods of analysis: limit analysis and limit equilibrium methods.

3.Collapse of the soil masses: earth pressures, bearing capacity of shallow foundations; collapse of slopes.

4.Verification of safety of geotechnical structures to the ultimate limit states: Eurocode 7.

5. Verification of safety of shallow foundations; brief approach to deep foundations; verification of safety of slopes; verification of safety of earth retaining walls.

5.Displacements of geotechnical structures; settlements of shallow foundations.
