为指导预制装配式车站结构抗震设计，以长春预制装配式车站为背景，采用地下结构抗震分析Pushover分析方法的基本原理，基于ABAQUS有限元软件，考虑土-结相互作用，分别建立装配式地铁车站结构和同型现浇结构的土-结相互作用有限元分析模型，对比分析不同地震烈度下2种结构内力分布趋势与大小差异的规律及原因。研究结果表明： 1）2种结构内力分布趋势相同，构件峰值弯矩及反弯点位置一致，2种结构的峰值弯矩均出现在顶拱拱肩、顶拱跨中、侧墙与底板交接部位； 2）装配式车站结构各构件的峰值弯矩较现浇结构明显减小，峰值弯矩最大降低幅度约50%，装配式车站结构接头弯矩较现浇结构对应部位弯矩显著降低，最大降低幅度约70%； 3）在水平地震作用下，装配式车站结构非刚性接头率先变形，释放了接头弯矩，降低了接头弯矩和预制构件的峰值弯矩，有利于结构抗震设计。

To guide the seismic design of 〖ＪＰ２〗prefabricated structure of a metro station in Changchun, China, the basic principles of Pushover analysis method and ABAQUS finite element software are adopted to establish soilstructure interaction finite element analysis models of prefabricated and castinplace metro station structures. The internal forces of the two kinds of structures under different seismic intensities are compared and analyzed to study the law and reason of difference in internal force under horizontal earthquake. The results show the following: (1) The internal force distribution trend, the peak bending moment of the components, and the position of the reverse bending point of the two structures are the same; the peak bending moments of the two structures appear at the top arch shoulder, the middle of the top arch, and the junction between the sidewall and the bottom plate. (2) Compared with the castinplace structure, the peak bending moment of each component of the fabricated station structure is significantly reduced and the maximum reduction range of the peak bending moment is approximately 50%; the joint bending moment of the fabricated station structure is significantly lower than that of the corresponding part of the castinplace structure and the maximum reduction range is approximately 70%. (3) Under the action of horizontal earthquakes, the nonrigid joints of the fabricated station structure are deformed first, which releases the joint bending moment, and reduces the joint bending moment and the peak bending moment of the precast members, which is conducive to the seismic design of the structure.
