Geotechnical Earthquake Engineering/Slope stability and Landslide Risk Mitigation (Geotechnical Earthquake Engineering)

The dynamic response of the subsoil has a strong influence on seismic risk. Indeed it affects the seismic hazard and the soil-foundation-structure interaction. The course, after the introduction of the basics of seismology and soil dynamics, deals with geotechnical issues of engineering structures under seismic loads.

Geotechnical Earthquake Engineering/Slope stability and Landslide Risk Mitigation (Slope stability and Landslide Risk Mitigation)

The course aims to provide the necessary knowledge to evaluate the stability conditions of slopes in rock and soil, both natural and artificial. To this end, the various mechanisms of instability and the various analytical and numerical methods to be used in static and dynamic conditions are described. The elements are then provided for the selection and design of structural mitigation measures aimed at slope stabilization and for the evaluation of the contribution provided by the monitoring systems to the study of slope stability.

Geotechnical Earthquake Engineering/Slope stability and Landslide Risk Mitigation (Geotechnical Earthquake Engineering)

The exam is composed by an homework in 3 parts and an oral exam. The homework is intended to provide the practical skills necessary for the quantitative assessment of seismic hazard at a site, including the evaluation of the stability of a retaining structure, which will consider also the evaluation of its performances. The oral exam is intended to evaluate the comprehension of the background theory and to assess the full understanding of the topics covered by the homework.

Geotechnical Earthquake Engineering/Slope stability and Landslide Risk Mitigation (Slope stability and Landslide Risk Mitigation)

The exam consists of four projects and an oral exam. Each project has to be carried out during computer lab hours and completed at home. Students will work in small groups and have to deliver the work at fixed dates. To access the oral exam, all the projects have to be made in due time. Object of the oral exam will be both the projects and the topics dealt with during the lectures. The student has to demonstrate understanding of all the subjects and has to be able to defend the choice made in each of the projects. The final mark will be based on both the quality of the delivered projects and the outcome of the discussion during the oral exam.
