摘要:: 为了合理开发、利用地下空间资源,目前国内出现了一种新型的地铁车站结构形式:侧向连续开孔的地铁车站结构。因为车站边墙的开孔会削弱结构的整体抗震性能,所以有必要研究该结构形式的抗震能力。对侧向连续开孔的地铁车站结构建立了三维计算模型,通过研究其三维地震响应规律,确定了结构的薄弱部位,得到了地震荷载引起的结构内力的增幅。该研究成果可为今后此类地铁车站结构的抗震设计提供参考。

Abstract:: In order to rationally utilize and exploit underground space,a new structural style,subway station structure with continuous holes in lateral wall,appeared in subway construction.But the continuous holes in lateral wall weaken the whole seismic ability of structure,so it is necessary to study this structural style.We build the 3D calculation model of this structure in the paper,study its seismic response rules,determine the unsubstantial part of the structure,and obtain the increment of structural internal forces caused by seismic load.The study results can provide reference for the seismic design of this kind of subway station structure in future.
