岩爆现象发生在岩体的静态稳定条件被破坏，动态破坏过程从平衡状态开始。考虑到在数值上确定失稳点的困难，本文提出了另一种方法：在求解初始静态问题后，通过叠加动态扰动来研究动态破坏的模式和发生。用这种方法，可以用比较简单的方法对冲击地压现象进行定量分析。
The phenomenon of rock burst occurs when the static stability conditions of the rock mass are violated and the dynamic failure process proceeds starting from the equilibrium state. In view of the difficulties in determining numerically the instability point, an alternative approach is advocated here: after solving the initial static problem the mode and onset of dynamic failure are studied by superposition of dynamic disturbances. In this way quantitative analyses of rock burst phenomena may be handled in a relatively simple manner.
