Abstract

According to the self-organizing characteristic of rock mechanics system during evolution, synergetics was applied to investigate the evolution process by taking dynamic disturbance into account, and a generalized dynamical equation was established. Based on analysis of phase transition theory and damage thermodynamics theory, the major parameters which affect evolution of rock mechanics system, including order parameter, control parameter and outer field were discussed and their expressions were given. The influence of dynamic disturbance on evolution and stability of rock system was analyzed using potential function method. The critical instability point and the relationship between control parameter, outer field and disturbance intensity were discussed. Results indicated that dynamic disturbance could not only decrease the stability but also induce the instability of a rock mechanics system under certain conditions. The critical instability point is together determined by disturbance intensity, differential stress and differential damage.
