Abstract

Under the effect of earthquake, loss of soil stiffness results in loss of bearing capacity which subsequently lost the support of basic structures that tilt and therefore pack down. The study of settlement of granular media under seismic loading, although it has not retained the attention of many researchers in the past, is crucial if we are to guarantee the good performance of embankments, dikes or land upon which some works at risk. Numerical simulation of soil behavior is performed by numerical methods such as finite difference and finite element method. These methods are programmed in software simulation of increasingly sophisticated. The main objective of this paper is to investigate, by numerical modeling with the code of finite element PLAXIS, variation in settlement of a soil under a rock fill dam port
