Learning outcomes
The course illustrates basic principles to study the behaviour of soil slopes and retaining structures. Course aims: ? to apply the background knowledge of soil mechanics and geotechnical engineering to real design problems; ? to give the students an opportunity to interpret real data sets and to select characteristic geotechnical parameters for design; ? to design slopes and retaining structures also by using professional software.

Program
Resume basic principle of soil mechanics: soil investigation, in situ and laboratory testing. Soil geotechnical properties: shear strenght, total and effective, peak, critical and residual strenghts. Monitoring. Slope stability: Instability processes: classifications, definition of the geotechnical model, slope stability analyses. Slope stabilization: structural remedials, drainages. Pratical work: analysis of a slope stability problem also by using professional software Retaining structures. Earth pressure theories, both in static and seismic conditions. Soil structure interaction models. Geotechnical design and technologies: earth walls, diaphragm walls and sheet piles. Anchors. Practical work: design of flexible earth retaining structures and of their anchors, also by using professional software.

Development of the examination
LEARNING EVALUATION METHODS
Path1. Written and oral examinations. Three hours are at student's disposal for written examination Path 2. Report of pratical work and oral examination. The pratical work is a geotechnical report pertaining to a real problem; the report will contain an interpretation of data sets useful to make an appropiate choice of strenght parameters and soil stiffness, a realistic geotechnical model, the geotechnical analysis according national code

LEARNING EVALUATION CRITERIA
Path 1. A first stage constituited by a written examination, followed by an oral examination. The minimum entry requirement for oral examination is a sufficient mark on written examination. Path 2. The student will discuss his pratical work, then will give an oral examination relating to other course topics. The students must justify exhaustively their geotechnical design choices.

LEARNING MEASUREMENT CRITERIA
Marks are expressed out of 30.

FINAL MARK ALLOCATION CRITERIA
Positive evaluation: suitable knowledge of topics and proper use of technical language. Full evaluation: in depth knowledge of course topics, mastery of technical language, ability to optimize a geotechnical design and to apply the knowledge gained in sister courses.
