英文摘要：

Based on the general principle of three-dimensional numerical manifold method, a model for rock anchor bolts is proposed and the corresponding algorithm and formulas are given. Stability analysis of rock slope shows that the model can better describe the deformation behaviors of anchor bolt-supported rockmass and the reinforcement effect of the anchor bolts.
