This paper aims to analyze slope stability based on the numerical simulation using Plaxis software. The mechanical parameters of soil layers constituting the slope are evaluated from laboratory results and numerical simulations of in-situ pressuremeter tests. The study of the slope consists to determine the failure surface and the corresponding safety factor. This coefficient is calculated taking into consideration the influence of factors that contribute slope instability and following the use of several methods of reinforcement to strengthen the slope.
