Risks of landslides and rock mechanics and Analysis of slope stability
Module Analysis of slopes stability

Academic Year 2022/2023 - Teacher: Giovanna PAPPALARDO

Expected Learning Outcomes

The course aims to provide the basic knowledge of the stability analysis of slopes in earth and rock, on the main methods of stability analysis, such as the limit equilibrium method, and to know how to evaluate the stability of slopes with the determination of the safety factor.

Course Structure

Generally the teaching takes place through lectures and practical lessons in the classroom, with the support of multimedia material (slides projected during the lessons) and handouts. Mandatory attendance.

The teacher will explain to the students the procedures for calculating some topics of the program.

If the teaching is given in a mixed or remote mode, the necessary changes with respect to what was previously stated may be introduced, in order to respect the program envisaged and reported in the syllabus.

Required Prerequisites

Course of Applied Geology, Applied Geophysics, Geomorphology.

Attendance of Lessons

Attendance to lessons is compulsory. For working students, reference is made to the University teaching regulations.

Information for students with disabilities and / or SLD:

To guarantee equal opportunities and in compliance with the laws in force, interested students can ask for a personal interview with the teacher in order to plan any compensatory and / or dispensatory measures, according to the didactic objectives and specific needs. It is also possible to contact the referent teacher CInAP (Center for Active and Participated Integration - Services for Disabilities and / or SLD) of our Department

Detailed Course Content

  1. Definition of the safety factor.
  2. Stability analysis by Markland and Matheson for the kinematics of planar slips, wedge slips and overturns.
  3. Calculation of the safety factor through the limit equilibrium method for the kinematics of planar and wedge slips.
  4. Calculation of the safety factor through the ashlars, Fellenius, and Bishop methods.

Learning Assessment

Learning Assessment Procedures

The final exam consists of an oral test and verification of learning of the topics covered in the practical tests performed during the course and the creation of a report at the end of the course on the measurements made during the external geomechanical exercise.

Verification of learning can also be carried out electronically, depending on health conditions and linked to Covid-19, in compliance with current University provisions.
