The strength properties of the rock under unloading conditions are essentially different from the rock under loading conditions. At present, the study on the mechanical properties of unloading rock mass is common, but the research for unloading strength properties of jointed rock mass, especially the influence of structural plane on unloading strength is seldom. The paper studied the failure characters of unloading rock mass, and the influences of structural plane properties on unloading strength based on triaxial test are considered emphatically. Finally the strength criterion of unloading rock mass is proposed in this paper.

Damage Equation

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.
