摘要

基于ABAQUS软件建立了地下地铁车站‑土‑上盖建筑一体化结构大型三维有限元数值模型，计算分析了上盖一体化地铁车站结构的地震响应规律和破坏机理，探讨了上盖一体化地铁车站结构与单体车站结构地震响应的差异。结果表明：地铁上盖一体化结构体系各阶自振频率与自由场地较为接近，地铁上盖结构的存在对场地动力特性的影响较小；强震作用下，一体化地铁车站结构的损伤破坏区域主要是车站各层楼板和墙柱的交接位置，尤其是中柱和侧墙顶底部的损伤最为严重；单体车站与上盖一体化地铁车站结构地震响应规律存在一定差异，上盖一体化地铁车站结构的地震反应略小，其中，上盖地铁车站结构的地震响应同时受上盖结构和周围土体介质的影响，上盖结构对上盖地铁一体化区域的影响显著，周围土体对上盖地铁非一体化区域的影响显著。

Abstract

Based on the ABAQUS software， a large-scale three-dimensional finite element numerical model of the underground subway station-soil-superstructure integrated structure was established. The seismic response law and failure mechanism of the superstructure integrated subway station structure were calculated and analyzed， and the differences in seismic response between superstructure integrated subway station structures and monolithic station structures were discussed. The results show that the natural vibration frequency of each order of the integrated structure in the subway superstructure is relatively close to that of the free site， and the presence of the subway superstructure has little effect on the dynamic characteristics of the site； The damage and destruction area of the integrated subway station structure is mainly distributed in the location of the intersection of the floor slabs and wall columns under the effect of strong earthquakes， especially in the location of the center column and the top and bottom of the side walls. The seismic response of the monolithic station structures and the integrated subway station structures is different. The seismic response of the integrated subway station structure is slightly smaller. The seismic response of the superstructure subway station is simultaneously affected by the superstructure and surrounding soil medium. The superstructure has a significant impact on the integrated area of the superstructure and the surrounding soil obviously affects the non-integrated areas.
