ABSTRACT: Seepage plays a significant role in many geotechnical problems such as the stability of earth dams and riverbanks. In addition, the large-deformation behavior of soil is equally important in many cases, including progressive failure of slopes, and landslides in sensitive clays. The large-deformation can be successfully simulated using Eulerian-based finite-element (FE) modeling techniques. In the present study, a technique is developed for a Eulerian-based FE analysis using Abaqus FE software to simulate both transient and steady-state seepage through an earth dam. The FE simulation results, including the seepage, in-situ stresses and slip surface in slope stability analysis, are compared with the analyses using the GeoStudio software package. In terms of practical implication, the developed seepage model could be coupled with the large-deformation FE technique in Abaqus to simulate the progressive failure of a riverbank.
RÉSUMÉ: Les infiltrations jouent un rôle important dans de nombreux problèmes géotechniques tels que la stabilité des barrages en terre et des berges des rivières. De plus, le comportement du sol en grandes déformations est tout aussi important, y compris la rupture progressive des pentes et les glissements de terrain dans les argiles sensibles. Les grandes sur Eulerian. Dans la présente étude, une technique est développée pour une analyse FE basée sur Eulerian utilisant le logiciel Abaqus FE pour simuler des infiltrations transitoires et stables à travers un barrage en terre. Les résultats de la simulation FE, y compris l'infiltration, les contraintes in situ et la surface de glissement dans l'analyse de la stabilité des
