The Research On Synergetic Dynamical System Of Evolution Of Rock Mass Damage

By the use of synergetic including its micro and macro approaches to study rock damage evolution under the loaded rock. Study the interaction between the surfaces of rock mass, block the displacement relative of the equilibrium position as the order parameter, use elimination method to establish the dynamic system model of evolution of rock mass damage, and finish stress analysis of rock mass. Then external manifestations from rock mass damage-starting from the phenomenon of the AE to research the law of rock mass damage, using the gray model to treatment the data which is collected about the AE, establishing the model of synergetic dynamical system of evolution of rock mass damage and using numerical simulation, we verify the synergy in rock acoustic emission, which further confirm the accuracy and feasibility, and provides a theoretical basis toward its engineering application.
