摘要
在以往地铁隧道的地震反应分析中 ,地震作用一般以水平剪切为主 ;本文在分析日本阪神地震中隧道的破坏模式的基础上 ,研究竖向应力对建筑物的作用 ,从而提出一种考虑竖向应力作用的简易计算方法。文中以上海地铁一号线隧道为例 。
The horizontal shear was taken as the main earthquake action in earthquake response analysis for subway tunnel.In this paper,on the basis of failure mode analysis of subway tunnel during Kobe earthquake in Japan,the effect of vertical stress to buildings is studied,and a simple calculating method considering the action of vertical stress is presented.Detailed analysis of a tunnel of Shanghai subway Route No 1 is given as an example of the proposed method.
