The course aims at the evaluation of the stability of natural and man-made slopes, cuts and excavations. The first part of the course focuses on the identification of landslide types and processes and the causes of movement in soil and rock slopes. Particular attention is given to the role of rainfalls in landslide triggering. The second part of the course focuses on: 1) the engineering methods used to analyze slope stability for the different kinematisms; 2) the strength parameters to adopt in the analysis; 3) improvement of the safety factor

The student must know the fundamental principles of Physics I; Applied geology; Hydraulics; Geomechanics. In particular the main principles of soil mechanics are considered a compulsory prerequirement and are not explained in class. In the web site of the course recorded lectures on these main principles of soil mechanics will be available.

The course is organized in theoretical lectures and practical lessons. During the practical lessons the students have to solve exercises by applying the theory explained in lectures. Two practical lessons are devoted to verify the stability of a slope with a software. Each student has to calculate the safety factor of a slope with given paramenters. A global sensitivity analysis, based on the the students' calculations is carried out.

Modalità di esame: Prova orale obbligatoria;
Exam: Compulsory oral exam;
The exam is aimed at evaluating knowledge, competences and skills acquired during the course. The student should be able to carry out stability analyses, to select strength parameters and to evaluate the effect of water pressure in a given case. The exam consists of a written test, closed books. The use of mobile phones or PDAs is not allowed during the exam. A pocket calculator is required. The test is organized as follows: - Multiple-choice questions (8/30 points). These questions are aimed at evaluating the general knowledge of the student acquired during the course - Two open questions (8/30 points). These questions, to be contained in not more than 2 A4 pages, are aimed at evaluating the ability of the student to discuss topics explained in class - Three exercises (14/30 points). The exercises are aimed at evaluating the skills of the students in solving practical problems The duration of the exam is 2 hours
Gli studenti e le studentesse con disabilità o con Disturbi Specifici di Apprendimento (DSA), oltre alla segnalazione tramite procedura informatizzata, sono invitati a comunicare anche direttamente al/la docente titolare dell'insegnamento, con un preavviso non inferiore ad una settimana dall'avvio della sessione d'esame, gli strumenti compensativi concordati con l'Unità Special Needs, al fine di permettere al/la docente la declinazione più idonea in riferimento alla specifica tipologia di esame.
Exam: Compulsory oral exam;
The exam is aimed at evaluating knowledge, competences and skills acquired during the course. The student should be able to carry out stability analyses, to select strength parameters and to evaluate the effect of water pressure in a given case. The exam will be oral in a classroom of the Politecnico di Torino. A calendar will be published on the course page after the term for exam enrollment and every day a group of students will give the exam. The oral exam comprises 3 main questions. Questions are related to the topics explained in class. Questions consist of discussion of a given topic and/or the solution of a practical exercise.
In addition to the message sent by the online system, students with disabilities or Specific Learning Disorders (SLD) are invited to directly inform the professor in charge of the course about the special arrangements for the exam that have been agreed with the Special Needs Unit. The professor has to be informed at least one week before the beginning of the examination session in order to provide students with the most suitable arrangements for each specific type of exam.
