the paper presents a numerical analysis of the seismic behaviour of earth dams . Analysis is conducted by finite difference modeling of the earth dam using the software FLAC3D for the solid phase it corresponds to the response of the dam before water filling . analysis is first conducted for a simple case which concerns the elastic response of the dam. this analysis provides some indications about the response of the dam mainly the dynamic amplification it is also useful to understand the influence of plasticity on the dam response . also the paper concerns a more realistic analysis of the dam where the elastoplastic behaviour of the earth material is considered.
