Abstract

Abstract

Stability analysis of the high-steep rock slope focus in research and engineering sectors for a long time because it has been considered as the reason why geological disasters occurred such as slope instability and landslide. Taking the slope in Qianling Mountain in Fengtai District in Beijing as an example, parameters by rock mechanics experiment was obtained by combining with the real internal structure of rock mass which measured by geological radar. Geomechanical model of the slope has been established, and the safety factor was obtained through this model by the strength, and at the same time the whole evolutionary and the location of the critical failure surface can be found directly. Clearly, the applicability of this new method has practical value for the stability analysis of high-steep rock slopes.
