Etude de la stabilité des fondations superficielles sur talus sous chargement sismique réel par une approche dynamique globale

The aim of this paper is to analyze the slopes stability under seismic loading using a global numerical dynamic approach. The present study is conducted by using measures recorded during real earthquakes. A parametric study according to the reinforcement length, position, inclination and the number of elements has been studied in order to define the optimal reinforcement scheme for slopes under seismic loading. This study contains also the stability analysis of an existing foundation near the slope’s crest. It will focus on the reinforcement in order to give recommendation for the most appropriate scheme that minimize the settlement of the foundation due to earthquake effect.
