A new method of inflicting equivalent pre stress is suggested to simulate mechanism on reinforcement of pre stress anchor cable on crack prevention of different angle by mini-plastic zone displacement by finite element method. The change rule of displacement of middle points of crack faces, the change of stress strength gene and strain is compared under different pre-stress consolidated condition. When the angle of crack is 450, the consolidated role of rock mass is the best evident. The effect of compression of jointed rock mass is larger than the effect of shear under pre-stress consolidated condition.
