摘要

以苏州地铁一号线的星海站为工程背景

考虑土与地铁车站结构非线性动力相互作用效应

分析了土与地下结构接触面的动力分离与滑移效应、土与地下结构接触面上动土压力和动摩擦力的分布规律与反应幅值

以及动力接触效应对地铁车站结构动力反应的影响规律。研究结果表明:强地震发生时

在地铁地下车站结构侧墙顶端

出现了土与结构接触分离现象

在车站结构顶底板处

土与结构产生了相对滑移现象;考虑动力接触效应时

地下结构总体动力反应是变小的。给出了车站结构侧墙上动土压力分布规律及其动土压力系数

以及车站结构顶底板上的动土压力分布规律及其反应幅值。研究结果对进一步了解土与地下结构的动力接触效应及其对地下结构动力反应的影响

具有一定的参考价值和指导意义。

Abstract

Based on the engineering background of Xinghai station of metro line 1in Suzhou city

considering the nonlinear dynamic interaction of soil-subway station structure

the following is analyzed mainly in this article:the dynamic separation and slip effect of the interface between soil and underground structure

the response amplitude and the distribution law of dynamic earth pressure and dynamic friction and the influence of dynamic contact effect on the dynamic response of subway station structure.The results show that soil and subway station structure are found separated on the top of the side wall and relatively sliped on the structure roof;meanwhile

the general dynamic response of underground structure is smaller when considering the dynamic contact effect.The distribution law and coefficient of dynamic earth pressure of the side wall are given in this article.The response amplitude and the distribution law of dynamic earth pressure of the structure roof are also given.These analysis results have direct reference value and guiding significance for further understanding the dynamic contact effect of soil-underground structure and its effect on dynamic response.
