摘　　要：[目的]当前,我国装配式地下车站结构体系呈现多样化发展特征,但缺乏系统梳理,故对明挖法装配式地下车站的结构性能研究进展进行梳理。[方法]针对当前主流的结构形式,系统总结了明挖法装配式地下车站结构体系特点;从预制构件、节点连接和整体结构等3个层面梳理了明挖法装配式地下车站的结构性能研究情况;提出了明挖法装配式地下车站的发展方向。[结果及结论]明挖法装配式地下车站结构可分为装配整体式和全拼装式两种;装配式地下车站预制构件的研究主要集中于装配式板类构件的承载性能;预制构件的节点连接,关系到装配式地下车站整体结构的承载和抗震性能,是研究的重点;装配式地下车站结构承载和抗震性能主要通过数值分析手段进行研究,较为缺乏整体结构的试验数据;考虑全寿命周期的装配式地下车站受力性能研究将成为重要研究方向。[Objective]At present,the structural system of prefabricated underground stations in China presents diversified development characteristics,but lacks systematic classification.Therefore,the research progress on the structural performance of open-cut prefabricated underground stations is sorted out.[Method]Aiming at the current mainstream structure forms,the structural system characteristics of open-cut prefabricated underground stations are systematically summarized.The research on the structural performance of the above stations is organized from prefabricated elements,joint connections and overall structure three levels.The development direction of open-cut prefabricated underground stations is proposed.[Result&Conclusion]The structure of open-cut prefabricated underground stations can be classified into two categories:prefabricated-monolithic type and fully-assembled type.The research on prefabricated components of assembled underground station mainly focuses on the bearing performance of assembled plate components.The joint connection of prefabricated components is related to the bearing and seismic performance of the overall structure for the prefabricated underground station,and therefore is the focus of the research.The bearing and seismic performance of prefabricated underground structures is mainly investigated by numerical methods,and lacks experimental data on the overall structure.Studies on the load bearing performance of the above station considering the whole life cycle will become an important research direction.
