Modeling the Seismic Behavior of Bituminous Faced Rockfill Dam with Hujeux Model Implemented in Code_Aster

Abstract

This article presents a simulation of the static and dynamic behaviour of a bituminous faced rockfill dam with the Hujeux constitutive model and the methodology originally developed on code_aster for dams made of saturated granular materials. The calibration procedure of the parameters is carried out on the basis of available tests and static and dynamic results are presented for two seismic signals with different frequency contents. Results are compared with correlations available in the literature. The discrepancies are analysed in terms of the functioning of the behaviour model.
