drained and undrained analysis in seismic response of earth dams

the paper presents a numerical analysis of the influence of the water skeleton interaction on the response of earth dams to seismic loading. Analysis is conducted by finite difference modeling of the earth dam using the software FLAC3D. Analysis is first conducted for a simple case which concerns the elastoplastic behaviour and drained condition of the dam. it corresponds to the response of the dam before water filling. also analysis is conducted under undrained condition which corresponds to a simplified analysis of the response of the dam. this analysis does not provide the variation of the pore water pressure it constitutes a first stage of the analysis of the seismic response of the dam in total stresses.
