A damage mechanics model for jointed rock mass is established by the simulation of the multi-cleavage behaviour by introducing the damage tensor and by considering the jointed rock mass as continuous medium with damage. The data exchange technique with FLAC-3D is discussed by applying FISH Language that is inserted in FLAC-3D. The coupling analysis between the rock mass damage and FLAC-3D is realized by the computer program for damage mechanics analysis set up by Visual Basic, which is applied in the simulation analysis of the south slope of Yanqianshan Iron Mine.

The jointed rock mass distributed in the nature widely and its mechanical characteristic influenced the stability of the rock engineering badly. The cracks propagated and coalesced each other and macroscopic failure happened. Bolts were a kind of effective reinforcement instrument and they could prevent the cracks from propagating. However, the anchoring mechanism of bolts was not realized clearly and their reinforcement could not be reflected effectively in the numerical simulation yet. Based on the damage mechanics, a constitutive relation and damage equation of anchored jointed rock mass were presented in this paper. With a project application, the model was proved to be feasible one.
