Energy Releasing Illustration of Rock Destabilization Based on Catastrophe Theory
Based on the Catastrophe Theory, the catastrophe model of rock destabilization educed by equilibrium relation of work-energy increment from energy conservation principle belongs to the fold catastrophe model. Condition and process of rock destabilization were analyzed, and rock destabilization critical condition was given, the end of rock destabilization is confirmed strictly. The energy importing rate J=0,system destabilization critical condition, implicates Cook stiffness criterion, Using energy importing rate, understanding in the stability of rock stability can be improved from qualitative understanding to quantitative description. The elastic energy releasing illustration given in paper contain rich amount of information and have great significance in understanding the behavior and law of rock destabilization.
