Abstract：
In order to grasp the dynamic deformation characteristics and the influence of prestressed cable reinforcement on the excavation process, this paper takes the concrete rock slope engineering as an example, using FLAC3D simulation to analyze the deformation characteristics of the excavation process and the deformation characteristics of the rock slope. The results show that the excavation is easy to cause the local rock mass destruction; the safety factor of the rock slope is improved by 21.3% because of using prestressed cable; the scheme of edge excavation and support can very well constrained rock mass horizontal displacement, and effectively improve stress distribution of the slope.
