Subject fundamentals
Geotechnical earthquake
The dynamic response of the subsoil has a strong influence on the 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.

Slope Stability
The course aims to provide the knowledge necessary for the evaluation of the stability conditions of soil and rock slopes, in presence of both natural and man-made slopes. The different instability mechanisms are described, together with analytical and numerical methods to use in static and dynamic conditions. Basis for selection and design of structural protection systems are given and contribution of monitoring systems in slope stability are discussed.
Expected learning outcomes
Geotechnical earthquake
Understanding of the seismic response of soil deposits and its influence on the seismic hazard for the construction site. Ability to build simplified models for the prediction of the seismic response of site, the analysis of seismic hazards and the analysis of soil-structure interaction.

Slope Stability
Capability to identify typical landslide kinematics, to select and apply the more appropriate stability analysis method (as a function of the characteristics of the phenomenon to be investigate) and to select mitigation and stabilization techniques.

Delivery modes
Geotechnical earthquake
Practical examples will be presented in the classroom to make the students familiar with the topics of the course. Some practical examples will be devoted to the use of computer softwares for the numerical simulation of geotechnical earthquake engineering problems.

Slope Stability
The course consists in lectures and exercises.
On the basis of the theoretical aspects that are taught during lectures, students are given some homework to solve. Each homework can be carried out by groups of a maximum of three people.
Students have to return the assigned exercises by the deadline fixed. In case of delay, exercises will not be corrected and evaluated and will contribute negatively to final evaluation.
The above exercises, some of which to be solved using the software available in the Politecnico Informatics Laboratory, will concern: Italian landslide inventory, interpretation of monitoring systems data, toppling, Limit Equilibrium Methods application to slope stability, numerical modelling of rapid landslide propagation, design of structural mitigation systems (e.g. draining systems).
