The course aims at introducing the student to the principles of soil mechanics and to the study of the mechanical behavior of structures interacting with the ground.
The student shall acquire the necessary skills to the design and assessment of a geotechnical work. These skills will be achieved through the understanding of concepts such as:
1. distribution of the stresses between the constituent phases (the principle of effective stresses);
2. distinction between coarse-grained and fine-grained materials, drained and undrained states and practical implications;
3. peak strength, dilatancy, critical state;
4. problems of limit analysis;
5. influence of geological and stress history on the response of natural materials;
6. design and assessment of geotechnical structures.
At the end of the course, the student will be able to master the basic tools necessary to the design of geotechnical works, from the design of in situ and laboratory test campaign to the definition of the geotechnical model
Mechanics of Materials and Structures
Lectures and tutorials in classroom.
Laboratory and site experiences.
Seminars.
1,5 hours written exam aimed at verifying the understanding of the topics covered by the course, by means of three exercises that require the application of the concepts discussed during the course to the solution of geotechnical problems. The three exercises have the same value in terms of scoring.
Successful students will have to take a subsequent oral exam focused on the theoretical topics discussed during the course, starting from a topic of their choice.
1. Description and classification of soils
Origin and geological/depositional history of soil.
Phases and relations between phases.
Grain size characteristics and index properties.
Characteristics of natural deposits.
2. Behavior of the element of volume
Effective stresses, geostatic stresses.
Normal consolidation and overconsolidation.
Oedometer test; application to the calculation of one-dimensional settlements.
Strength of coarse grained and fine grained soils: failure criteria and stress-strain behaviour.
3. Mechanical characterization of soils
Standardc laboratory tests (TX, DS).
In situ tests (surveys, SPT, CPT, CPTU).
4. Boundary problems
Seepage in porous media.
Steady state seepage.
Theory of consolidation.
Limit equilibrium. Stability analysis of rigid and flexible retaining structures.
There will be no differences in preparation between attending and non-attending students.
All the topics of the course will be presented through slides available to students in pdf format.
The exercises carried out at the blackboard will also be made available in pdf format.
