Abstract

The stability of an embankment is analyzed by determining its safety factor. The present work consists of analyzing the effect of atmosphere-soil interaction on the stability of the embankment located in the Ngamakosso district (Talangai, Brazzaville, Congo Republic). The aim of this work is to carry out an in-depth study of this embankment using the finite element method in order to evaluate its stability. The study of the stability of natural slope using finite element method gave a low safety factor showing that the slope is unstable. However, earthworks by softening the slope angle as well as the establishment of vetiver-type plant cover had appositive influence and constituted an effective means of stabilizing this slope. The results obtained after these analyzes indicate that the embankment is in a satisfactory state of stability.
