In the proceedings of: GeoVirtual 2020: 73rd Canadian Geotechnical ConferenceABSTRACT: In this study the step by step procedure is introduced to evaluate the dynamic behavior of an embankment dams under seismic loading, using a coupled energy-based pore pressure model. The simulated dam with 12 m height was assumed to be in Saguenay region as one of the most seismically active regions of eastern Canada. To define the dynamic behaviour of constituent materials of the simulated dam the energy-based model was combined with Sigmoidal-model in FLAC 2D software. The proposed models were developed, calibrated and verified based on a series of stress-controlled cyclic direct simple shear (DSS) tests performed on representative constituent materials of the dam at the Université de Sherbrooke. The results of all dynamic simulations using different implemented ground motions were compared and the dynamic behavior of the dam under seismic loadings was evaluated.
