两种等效爆破载荷作用下岩质边坡的

he rock explosion is a complex transient process, and its determination is difficulty. Making assure the blasting load is basis on analysis of dynamic response of rock. In this paper, FLAC3D was adopted to simulate two different forms of blast loading, and monitoring the results with field results then comparing them. The imposed different methods of blasting load，corresponding numerical simulation results show that in the near field which there are some differences, but coinciding better in further area. Finally，given the application scope of both methods.
