结合某正在规划中的相互穿越地铁车站结构,考虑单个地铁车站和两个交叉地铁车站的情形,分别建立各自的计算模型,计算在该地区人工地震波作用下地铁车站的地震响应,分析交叉地铁车站的地震响应规律以及两交叉地铁车站地震响应的相互影响规律。计算分析表明:该交叉地铁车站满足该地区的抗震要求;浅层地铁车站的相对变形要大于深埋地铁车站;下层地铁车站的相对变形较小,柱端弯矩较小,但由于埋深大,其底板弯矩较大;下层地铁车站的存在为上层地铁车站起到了一定的隔震作用。研究成果可为地下相互穿越工程的抗震设计提供参考。
Considering the structure of a metro station that is planning to go through each other and considering the situation of a single metro station and two metro stations, respectively, to establish their own calculation model to calculate the seismic response of the metro station under artificial seismic waves in the area, and to analyze the cross metro station The law of earthquake response and the interaction between the two subway stations. The calculation and analysis show that the cross metro station meets the seismic requirements of the area; the relative deformation of shallow metro station is greater than that of the deep metro station; the relative deformation of the lower metro station is small and the bending moment at the column end is small; , The floor bending moment is larger; the existence of the lower metro station plays a role of isolation for the upper metro station. The research results can provide a reference for the seismic design of underground cross-over projects.
