Aim\ To obtain response rule of the underground structure under blasting stress waves. Methods\ Based on experimental results
by mean of non linear FEM
computer simulation of the underground structure under blasting stress waves is made. Results\ Simulation result is will correspond to experimental result. Conclusion\ There are two main aspects: (1) Propagation rule of media nodes: the effective velocity value duration is increased as the distance increases between the node and the blasting source. (2) Response rule of structure: Vibrating velocity in the vertical direction is the main portion for the underground structure nodes.
