Numerical Analysis of Deformation and Stability of Rock Slope under Rainfall Condition

Abstract:

Combining an example of rock slope engineering, the finite element model of excavation, reinforcement with rainfall infiltration conditions is built up. The process of stage excavation and reinforcement of the slope are simulated, and the stress and deformation law and displacement change of the slope during each stage period are analyzed, and the stability of slope is evaluated under some conditions. Moreover, the discontinuous deformatioanalysis model is set up, the limited internal friction angle of the sliding face of slope is obtained, and the slope stability is evaluated. It was shown that the conclusion of two methods was consistent, and the slope was basically stable.
