Subject fundamentals
The course provides the tools necessary for the analysis and design of the most common foundation structures, such as shallow (footings, beams, mats) and deep foundations (piles). The design of retaining walls (gravity and cantilever walls), diaphragms and sheet-piles is also introduced .


During the course, the students will learn:

- to evaluate the bearing capacity and settlements of shallow foundations and to make the structural design of pad foundations;
- to evaluate the effects of soil-structure interaction on structural response (with special reference to mats and beams foundations),
- the main techniques that can be adopted in the construction of foundation piles and the related problems;
- to determine the axial capacity of single piles;
- to evaluate the displacements and stresses induced on a single pile by axial and lateral loads;
- to analyze the behavior of pile-foundations, taking into account the interaction effects;
- to evaluate active and passive earth thrust against retaining walls and design the different earth retaining structures.
Expected learning outcomes
The expertise to be gained during the course includes:

- the capacity of identifying the most appropriate type of foundation to carry the load of a given structure resting on a deposit with given geotechnical characteristics;
- the skills needed for the geotechnical and structural design of shallow and deep foundations and of retaining walls;
- knowledge of the main construction and monitoring techniques that can be used for the construction of piles;
Prerequisites / Assumed knowledge
Students attending the course must have profitably followed courses on Soil Mechanics, Strength of Materials and Structural Engineering.
Contents
Introduction (approx. 8 hours)
The course begins with a general review of the problems encountered during the geotechnical characterization of a site and the description of the procedures used in site investigation and in-situ testing.

Shallow foundations (approx. 36 hours)
The geotechnical and structural design of shallow foundations (footings, beams, and mats) is introduced through the following steps:

- evaluation of the bearing capacity of shallow foundations resting on coarse and on fine graded soils;
- evaluation of the settlements of shallow foundations resting on coarse and on fine graded soils;
- evaluation of internal actions and structural design of footings;
- analysis of beam resting on elastic springs (Winkler) and on elastic half space (Boussinesq);
- soil- structure foundation interaction problems;

Deep foundations (approx. 24 hours)
The geotechnical and structural design of deep foundations considers the following aspects:

- the main types of deep foundations and the associated construction techniques;
- the methods used to evaluate the capacity of driven and bored piles, both in coarse and fine graded deposits;
- the methods for the evaluation of pile settlements;
- the analysis of interaction phenomena among piles in a group;
- the structural design of piles and pile caps;
- the analysis of transversally load piles and the evaluation of the induced displacements and actions;
- the analysis of the behavior of a pile foundation;
- the design and interpretation of load tests on piles.

Retaining walls (approx. 20 hours)
The following aspects are covered:
- evaluation of active and passive thrust in coarse and fine graded soils (drained and undrained conditions);
- effects of soil-structure friction and of external loads;
- effects of water and filtration forces;
- stability analysis and structural desing of earth retaining structures.
Delivery modes
Guided exercises and practical examples will be solved in the classroom by the lecturers.
Students are requested to solve extra exercises alone.
