Prerequisites
Basic knowledge of analytical calculation, phisics and construction science.

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course aims to provide students with the tools needed to understand the hydraulic and mechanical behaviour of a soil and how it interacts with the structures in contact with it, and to provide the basic knowledge for designing of retaining walls and foundations.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The course is aimed at giving the students the basic knowledge of soil mechanics and geotechnical engineering. They are guided and required to solve simple geotechnical problems as the basic skill for a building engineer.
TRANSVERSAL SKILLS:
The course requires many skills given in previous courses. During the course the students are encouraged to a review of their basic knowledge and to work in groups to solve proposed exercises in order to improve their learning and ability to analyse the geotechnical problems.

Program
Basic characteristics and classification of soils. The principle of effective stress. Fundamentals of continuum mechanics. State of stress within a linear elastic half-space for different loaded areas. Steady flow through soil. Darcy’s law. Coefficient of permeability. Seepage force. Piping. Laplace’s equation and its solutions. Consolidation process. One-dimensional consolidation theory. Oedometer test. Compressibility and stress history. Preconsolidation pressure and overconsolidation ratio. Secondary compression. Stress-strain and strength characteristics. Lab soil testing (direct shear test, triaxial tests). Mechanical behaviour of sands and of clays. Shear strength parameters. In situ testing (CPT, SPT) Stability problems. Limit equilibrium method. Active and passive pressure. Earth retaining rigid walls. Bearing capacity of shallow and deep foundations and geotechnical design principles according to the italian rules. Settlements of shallow foundations on clayey and sandy soi. Different types of deep foundations. Bearing capacity of piles.

Development of the examination
LEARNING EVALUATION METHODS
Written test and oral examination

LEARNING EVALUATION CRITERIA
Written test: to evaluate students' ability in applying theory. Oral exam: to evaluate students' theoretical and practical knowledge.

LEARNING MEASUREMENT CRITERIA
Written test and oral exam are evaluated in thirtieths.

FINAL MARK ALLOCATION CRITERIA
The exam is passed if oral exam is sufficient. Errors in the written test, if any, are discussed during the oral exam. The oral exam is more important than the written test for the final mark. Full marks are assigned in case of correct written text and correct and brilliant oral exam with a proper technical language.
