摘要研究缓慢卸载P波诱发岩体不连续断裂破坏的机制，并用相应的试验方法和数值模拟方法探究了其诱发岩体不连续断裂破坏的可能性。针对开挖区围岩，建立一个在缓慢卸载P波作用下含1%孔隙率岩体的数值计算模型，其缓慢卸载的P波由钢板撞击岩体来模拟产生。模拟结果表明，如果岩体中有缓慢卸载P波，且其强度在一定范围内，岩体不连续断裂破坏的现象就会发生，隧道周边就会出现分区破裂化现象；而快速卸载的矩形波不能诱发围岩分区破裂现象。

Abstract：Slowly unloading P-waves and its function on this phenomenon has been investigated，and corresponding experimental study and numerical study have been implemented. A defected rock model around an excavation under the action of a slowly unloading P-wave is established，and the slowly unloading P-wave is induced by the impact of a steel plate. The simulation results show that if the strength of the slowly unloading P-wave is in a certain range，the phenomenon of discrete failures may occur in rock mass，and the phenomenon of zonal disintegration may be observed in the surrounding rock. And the rectangle stress waves cannot induce the phenomenon of rock discrete fractures.

Key words： rock mechanics rock discrete fracture zonal disintegration porous rock cracked zone
