摘要

应用LS-DYNA软件建立了北京比较典型的2层地铁车站有限元模型

通过数值模拟方法分析地铁车站发生内部爆炸时

爆炸波在地铁车站内部的传播规律。研究表明:①在0.3m/kg1/3<Z<1.6m/kg1/3范围内

车站内部超压峰值可用Henrych经验公式估算;②爆炸波在地铁车站的封闭空间不断出现反射、绕射现象

使得结构构件遭受多次冲击作用;③楼梯口起到了一定的泄爆作用。本文研究结果可供地铁车站的抗爆设计与安全分析参考。

Abstract

With increase of terrorist’s and accidental explosion events

the safety protection of subway station becomes a hot spot of society.The finite element model of a typical 2-floor subway station in Beijing was established by using software LS-DYNA to analyze the propagation regularity of blast waves under internal blast in subway stations.The results show that（1） the peak value of overpressure can be estimated by empirical Henrych formula for 0.3 m/kg（1/3）<Z<1.6 m/kg（1/3）;（2） the blast wave is reflected and diffracted in subway station

the structural members are subjected to blast impact repeatedly;（3） stair head has blast venting function.The above results may provide a reference to the blast-resistant design and safety evaluation of subway stations.
