摘要

目的　获取爆破地震波作用下地下结构物的响应特征 .方法　本文以试验结果为依托

采用非线性有限元分析手段

对爆破地震波对地下结构物的影响进行了数值模拟 .结果　数值模拟结果与试验吻合较好 .结论　得出两个主要结果 :介质质点振动速度的传播规律 (有效峰值持续时间

随传播距离的增大呈增大趋势 ) ;结构响应特征 (铅直振动是爆破地震波作用下结构振动的主要成分 )

Abstract

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.
