英文摘要：

The calculation method of the optimal anchorage angles for rock slope wedge is studied.By using equilibrium conditions of wedge body,Mohr-Coulomb yield conditions and boundary conditions of the structural planes,the optimal anchoring angle calculation method of rock slope wedge is put forward,in which the wedge slope safety coefficient is taken as the objective function.Then,the optimization strategy of mathematical programming problem is provided.This method can be convenient to get the optimal anchoring angle for wedges,and it has a clear concept,high calculation precision.So engineers and technicians can optimize the designs of the reinforcement of the wedge-shape body,thus reach the goal of safety and economy.
