L'objectif général de la thèse est la simulation numérique des mouvements forts du sol dûs aux séismes. Les déformations importantes du sol engendrent des comportements nonlinéaires dans les couches superficielles. L'apport principal de la thèse est la prise en compte de la nonlinéarité des milieux dans un contexte éléments finis Galerkin discontinus. Différentes lois de comportement sont implémentées et analysées. Le cas particulier du modèle élastoplastique de Masing-Prandtl-Ishlinskii-Iwan (MPII) est approfondi. Cette étude est divisée en deux parties. Une première qui vise à poser la structure du problème en présentant les équations et modèles utilisés pour décrire les mouvements du sol. Dans cette partie nous présentons également la mé...
