NUMERICAL SIMULATION OF THE HIGH ROCK SLOPE STABILITY UNDER THE COMPLEX FORCE CONDITIONS

In this paper, by using the FLAC procedure which is based on the finite difference method, we make a numerical simulation of high rock slope. Through the simulation of the four complex engineering conditions that contains before the slope excavation, after the slope excavation, under the bridge foundation load and under the anchor reinforcement, also considering the bridge foundation load's impact on the slope, We can get the slope displacement's change, the distribution of the slope plastic zone's changes and the change in slope stability factor, and then we can evaluate high rock slope stability. This paper focuses on the bridge foundation load's impact on the slope stability and the compensation impact of the cable reinforcement to the bridge foundation load’s negative effect on the slope stability.
