Abstract: In this paper ,the rock and mortar is simulated by solid mass element, the cable is simulated by structural element, the interface is setted between the rock and mortar, and the prestress is applied to the cable according to the new method in FLAC3D program，that is to say , the board in pressure diffusion anchor cable is simulated by structural element rather than the distributed loads gained by the theoretical analysis are applied to the board. And then the numerical simulation model of prestress anchorage is established, After that, the stress nephogram of the interface, rock and mortar mass is analysed; and then the axial stress along cable in rock mass, bond stress distribution between mortar mass cell and membrane, which is affected by pressure diffusion anchor cable are displayed more clearly.

Key words: pressure dispersion-type cable, numerical simulation, anchoring and reinforcing mechanism
