Abstract: Landslides are triggered around the world in different conditions, always are spectacular and often dramatic. The assessment and analysis of this problem is a very important act as risk prevention in geotechnical engineering. Many developments in geotechnical engineering research about applications, theory and practice to assess slope stability. All these improve the understanding of phenomena in realty. The researches of behavior of soils are also in development. There are numerous models of behavior of soils, from the elastic-plastic model to more sophisticated behavior models describing almost all aspects of elastic-visco-plastic behavior of soils. These models have been developed in order to be integrated into software. This article deals with the slope stability analysis, by the technique of shear strength reduction (SSR) coupled to the finite element method. Three criterions are used, the first is the Mohr–Coulomb failure criterion, and the second is the Hoek-Brown, the third is Drucker-Prager criterion. The factors of safety and the slide surfaces of this slope are analyzed by these criterions then compared and discussed. By making the comparative study, that can be captured and understood for appropriate use in engineering applications.
