Abstract
TIn contrast to soft land movements, rock instabilities appear to be very diverse due to the wide range of rigidities of rock materials and the variety of slopes affecting the massifs. In the rock masses, the discontinuities constitute the weak zones of the massif; they are the ones which essentially determine the behavior of the rock masses. In addition, discontinuities that favor the failure of the rock mass are added a potential factor which is the infiltration of water. An analytical study of the stability of the rock mass is carried out using the mechanisms of structural failure "plane, wedge and toppling". The Rock stability - Geostructural Analysis software was used to analyze the standard rock slope studied analytically. An interpretation of the results obtained is completed to better target the major parameters responsible for the instability of the rock masses.
