The Dynamic Behavior and Resistance of a Rockfill Dam using a Coupled Approach

This webinar will showcase a study, funded by Electricity of France (EDF), by Ali Haidar and Fabian Dedecker on the dynamic behavior and resistance of a rockfill dam with drystone pitching, modeled in FLAC3D and PFC3D using the coupled FDM (Finite Difference Method) — DEM (Discrete Element Method) approach.

The dam is located in the Pyrenees mountains in France. The main objective is to retrieve the dam’s response to a probable earthquake in this region and to quantify safety and stability levels in case of such an event. The crest settlement after the earthquake was analyzed and compared with the historical measures of similar dams. Two approaches were compared to quantify the seismic resistance of the dam: PGA (Peak Ground Acceleration) augmentation and SSR (Shear Strength Reduction).
