Dynamic stability analysis of the bedding rock slope considering the vibration deterioration effect of the structural plane

This paper focuses on stability analysis of an artificial rock mass slope by a nonlinear finite element method (FEM). For a long time, rock slope stability problem is always an important research issue in the field of geotechnical engineering, which is related to human life and property safety as well as engineering security and efficiency. Therefore, the stability analysis and evaluation on rock slope is of great significance. The static and dynamic stability analysis on the artificial rock mass slope of WuAn power plant in China is carried on respectively in this paper by using the strength reduction method and FLAC3D software. In this analysis, static and dynamic instability criterions are enumerated, and the static and dynamic safety factors are calculated with the developed criterions of the displacement mutation, respectively. The analysis results show that the artificial rock mass slope is basically stable. It indicates that analyzing slope stability with strength reduction method is feasible.

Stability Of Rock Slope

Aimed at stability of rock slope, the attitude of structural plane is statistically analyzed with a combined method of rose diagram and pole equidensite diagram, and the preferred structural planes which are dominant in stability of slope were further determined by a lot of factors such as the terrain and topographical features of slope, the lithologic characters and the development of structural plane. Besides, the stereographic projection method is applied to qualitative analysis for the stability of rock slope. The results show that preferred structural plane can effectively reveal the nature of rock slope stability and provide a dimensional discriminant approach for stability of rock mass slope.
