Comparative Study on the Influence of the Variation of Initial Stress on Slope Stability
The analysis of slope stability is one of the oldest research subjects in the geotechnical engineering field . 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.
