And then a potential function equation is derived from analysis of rock mass structure. Furthermore, by using potential function method, we analyzed the influence of dynamic disturbance on evolution and stability of rock system. The relationship between critical point of instability and parameters of control parameter and disturbance intensity is also discussed and a formula which can be used to forecast critical point of instability is derived. Results indicated that dynamic disturbance can not only decrease the stability of rock system but also induce its instability under certain conditions. Under same static states, stability and feasibility of disturbance induced instability might increase along with increasing of fluctuation intensity. The capability of destroying rock mass for a given disturbance is also effected by the state or control parameters of rock mass.
