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
