The Stability Analysis of a Slope under the Complex Conditions

Article Preview

Abstract:

The unstable failure of slope is frequent and the prevention is high difficult in the process of engineering construction. To provide reference for the prevention and control of slope landslide disaster, this paper take an engineer slope as the study background and make the strength stability analysis and evaluation of this slope. Through simulating different conditions by using the current comparatively mature limit equilibrium theory, analyzed and evaluated the stability of the slope under the conditions of precipitation, drainage and reinforced and master stability condition of this slope in the corresponding condition. The slope stability evaluation analysis results under different conditions showed that the landslide is more easily to take place under the conditions of natural state, heavy rainfall and earthquake. Slope stability improved in the drainage condition. At the same time, this paper combined the evaluation results of the analysis, putting forward prevention measures and suggestions for slope.
