Traditional open-cut and cast-in-place construction methods for subway stations result in significant social and environmental problems, failing to meet green construction and sustainable development requirements. The pipe-jacking method could solve these problems, with the advantages of mechanised trenchless construction and prefabrication. Based on the engineering project of the Shasan station of Shenzhen Rail Transit Line No. 12 in China, a novel structure scheme of the subway station constructed by the pipe jacking method are discussed, including structure segmentation, joint design, longitudinal connections, waterproofing, and construction procedures. Subsequently, the specimens were tested under twice the values of the designed loads to obtain the bending resistance and shear resistance characteristics of the joint. Moreover, a simplified solid element section-spring model for mimicking the behaviour of the joint was established and validated by the test results. The mechanical performance of the station structure was investigated using three-dimensional finite element analyses by incorporating a simplified joint model. The results indicate that the structure deformation and stress meet the code requirements, demonstrating the applicability of the novel structure scheme. The research provides a practical solution for the trenchless construction of prefabricated subway stations, contributing to sustainable development of urban underground space.

地铁车站传统的明挖现浇施工方式存在严重的社会和环境问题，不符合绿色施工和可持续发展的要求。顶管法可以解决这些问题，具有机械化非开挖施工和预制的优点。以我国深圳轨道交通12号线沙三站工程为背景，探讨采用顶管法施工的地铁站新结构方案，包括结构分段、节点设计、纵向连接、防水、施工程序。随后，试件在设计载荷值的两倍下进行试验，以获得接头的抗弯和抗剪特性。而且，建立了一个简化的实体单元截面弹簧模型，用于模拟接头的行为，并通过测试结果进行了验证。通过结合简化的连接模型，使用三维有限元分析研究了车站结构的机械性能。结果表明，结构变形和应力均满足规范要求，证明了新型结构方案的适用性。该研究为装配式地铁车站的非开挖施工提供了切实可行的解决方案，为城市地下空间的可持续发展做出了贡献。通过结合简化的连接模型，使用三维有限元分析研究了车站结构的机械性能。结果表明，结构变形和应力均满足规范要求，证明了新型结构方案的适用性。该研究为装配式地铁车站的非开挖施工提供了切实可行的解决方案，为城市地下空间的可持续发展做出了贡献。通过结合简化的连接模型，使用三维有限元分析研究了车站结构的机械性能。结果表明，结构变形和应力均满足规范要求，证明了新型结构方案的适用性。该研究为装配式地铁车站的非开挖施工提供了切实可行的解决方案，为城市地下空间的可持续发展做出了贡献。
