Research Progress on Structural Performance of Prefabricated Underground Station with Open-Cut Method
Year: 2024
Type: article
Abstract: 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.
