We start with an empirical approach through a geomechanical characterization of the massif was put in place to highlight the instability at the level of the various rock formations. then, a stability analysis was carried out using two different approaches: the analytical approach using the limit equilibrium method (Slide 6) and the numerical approach using two methods: the finite element method (Phase 2 ) and the finite difference method (Flac) in the static and dynamic case considering the state of dry and wet marls. The results show an optimal state of stability on the scale of the full profile north flank of the quarry and bad stability on the scale of the bench\u2019s of the different levels and the main facies of the potential slide is that of the marls.<\/jats:p>","DOI":"10.1088\/1757-899x\/960\/4\/042026","type":"journal-article","created":{"date-parts":[[2020,12,10]],"date-time":"2020-12-10T06:26:16Z","timestamp":1607581576000},"page":"042026","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":8,"title":["Slope
