本文将冲击地压发生过程视为包体与弹性围岩组成的力学平衡系统在外界扰动下的失稳现象.并论证了刚度形式的失稳准则. In this paper, the process of rockburst is regarded as the instability of the mechanical equilibrium system composed of the enclave and the elastic surrounding rock under the disturbances of the outside world, and the instability criterion of the stiffness form is demonstrated.
