摘要

In order to determine how a roadway withstands a momentum wave and de-termine the extent of damage to rock surrounding the roadway under different force wave peak impacts, the roadway dynamic response state was analysed using numerical simula-tion method. The roadway's critical peak force wave and fracture region under dynamic wave action were put forward. It is concluded that the method has practical value to road-way support and rockburst prevention.
