为了研究装配式地铁车站结构在倾斜可液化场地中的适用性，基于长春双丰站的工程实际，采用有限差分软件FLAC3D开展了可液化地层中装配式地铁车站结构的地震响应分析，分析了地基孔隙水压力、液化土体侧移、地铁车站结构的动力反应与上浮特征及装配式地铁车站结构的变形特点等。结果表明，倾斜可液化场地条件下装配式地铁车站两侧孔隙水压力呈现出靠近车站结构位置出现明显的负孔压现象，且结构左侧（上坡向）土体的负孔压明显大于右侧（下坡向）；地基土体距离车站结构越远，液化现象越明显；装配式地铁车站结构对周围土体侧移流滑有明显的抑制作用；上坡向侧墙（构件C1）主应力大于下坡向侧墙（构件C2），且结构上坡向侧墙底部主应力最大，因此在抗震设计时应重点注意结构上坡向侧墙。

The applicability of prefabricated subway station structures in inclined liquefiable sites was investigated. Based on the actual project of Shuangfeng subway station in Changchun City, the finite difference software FLAC3D was used to carry out the seismic response analysis of prefabricated subway station structures in liquefiable soil, for example, the pore water pressure of the foundation, the lateral motion of the liquefied soil, the dynamic response and uplift characteristics of the subway station structure, and the deformation characteristics of the prefabricated subway station structures were analyzed. The results show that the negative pore pressure phenomenon of pore water pressure on both sides of prefabricated subway station under inclined liquefiable site conditions is present, and the phenomenon becomes more obvious the closer the location of the station structure is to the station, and at the same time, the negative pore pressure of the soil on the left side of the structure (uphill) is significantly greater than that on the right side (downhill). The further away the foundation soil is from the station structure, the more pronounced the liquefaction is. The phenomenon of lateral slippage of the surrounding soil is significantly suppressed by prefabricated subway station structures. The principal stresses in the upslope sidewall (member C1) are greater than those in the downslope sidewall (member C2), and the principal stresses at the bottom of the upslope sidewall of the structure are greatest, so the upslope sidewall of the structure should be given priority in the seismic design.
