为研究装配式地铁车站结构型式和注浆式榫槽接头之间的力学性能影响关系，对比和分析了纯铰接接头结构、变刚度接头结构、刚性接头结构和现浇结构4种结构型式的内力和变形，并依托深圳装配式地铁车站结构方案选型，对比分析了高拱结构和坦拱结构对接头承载性能的影响。结果表明： 1）非刚性变刚度的注浆式榫槽接头对于预制构件弯矩的调幅作用明显，具有较好的变形能力。2）高拱结构的AB和BC接头安全余量较坦拱结构更大，但是顶拱接头安全余量表现弱于坦拱其他接头； 考虑到所有接头都处于线性阶段，综合考虑运输和投资等因素，最终选用坦拱结构。3）利用接头承载特征曲线对坦拱结构的各个接头承载能力进行验算，结果表明，接头均满足要求，且有较大的安全余量。

 The relationship between prefabricated metro station structure type and grouted mortisetenon joint performance is investigated by comparing and analyzing the internal force and deformation of four metro station structure types, i.e., pure hinged joint structure, variable stiffness joint structure, rigid joint structure, and castinplace structure. Furthermore, a comparative analysis is conducted on the influence of higharch and flatarch structures on the joints′ bearing performance based on the structural scheme selection of a Shenzhen prefabricated metro station. The results show the following. (1) The nonrigid grouted mortisetenon joint with variable stiffness and good deformation capacity has a noticeable amplitude modulation effect on the prefabricated component′s bending moment. (2) The safety margins of a higharch structure′s joints AB and BC are larger than that of a flatarch structure, and the top arch joint′s safety margin is weaker than that of flatarch structure joints. Considering that all joints are in the linear stage and the safety margin is enough, the flatarch structure is selected according to the comprehensive consideration of transportation and investment. (3) Each joint′s bearing capacity of the flatarch structure is evaluated using the joint bearing characteristic curve. The results prove that the joints meet the requirements, and there is still a large safety margin.
