Abstract

The analysis of slope stability is one of the oldest research subjects in the geotechnical engineering field [1]. The modelling of this stability is complex and remains a significant and unfinished research topic [2, 3]. The goal of this work was to study the influence of the variation of the initial stress field on the slope stability by the finite element method. The stability of a slope built with respect to three different configurations was studied through calculation of the safety factor using the Plaxis software. The first way of creating a slope consists of a progressive loading of the slope weight by a multiplying coefficient, the two other methods, take into account the chronology of the events and consist of performing cut slopes or fill slopes. Finally a comparison was carried out between the results of these studied cases.
