  • 摘要: 以北京实测地震波作为输入,运用二维显示有限差分程序对北京地区常见的3层3跨矩形断面结构地铁车站进行了动力模拟分析,探讨了纵横波时差耦合作用下车站结构加速度、位移放大效应及动应力变化规律。计算结果表明地震纵横波时差耦合作用导致浅埋地铁车站结构受力变形过程为:首先纵波作用使得结构产生较大的竖向加速度,导致结构产生一定的正应力;继而纵横波时差耦合作用使得结构产生较大的水平加速度,此时结构内力达到最大,容易使得结构产生较大的拉应力;最终随着地震动力作用逐渐减小至消失,结构内力减小,恢复稳定。在地震动力作用下,地铁车站侧墙、中柱等结构的加速度自下而上均发生放大效应,且竖向加速度的放大程度远高于水平加速度。因地震纵波产生较大的竖向加速度,并且具有较强的放大效应,需重视距离震源较近地区的地下结构竖向抗震性能;而纵横波时差耦合作用下,结构的内力往往能达到最大值,是地下结构发生破坏的主控因素。
