Course Description

The lecture covers methods of numerical analysis for dynamic behavior of the ground and geotechnical structures. In particular, the lecture covers mechanism, failure modes, and mitigation measure to geo-hazards. The lecutre ranges from mechanics of granular materials to numerical simulation.

Grading

Based on reports to excercises and attendance.

Course Goals

Successful students will have the ability to initiate their own research work on geo-hazards based on the solid understanding of the mechanics of granular materials and numerical analysis.
