L’évolution des méthodes de calcul en stabilité de pentes. Partie I : Méthodes à la rupture

Abstract

The evolution of slope stability methods Part 1 : Failure methods AbstractThis paper shows the evolution of the slope stability methods, useful for engineers in charge of quantifying a slope stability. We point out the hypothesis of the methods in relation with their relevant use. Dealing with failure methods, we start from Coulomb's corner, and show the progressive complexification and the multiplication of the methods, due to the upcoming of computers. However, no method can be considered as being the best, the user's know-how remaining the guarantee of their use.

Study of Slope Stability (Open Pit Mining, Algeria)

“…In this second case, the parameter values necessary to introduce in the calculation are normally given by the investigations already carried out on site, are real values such as: The geometry of the surface of the slide, the Geotechnical characteristics of the massive and the sliding surface, etc. In this case, the stability calculation also of great interest because it can identify the causes of the emergence of the movement and define the work of consolidating, devices necessary to limit the risk (Faure 2000).…”
