Abstract

The authors provide a systematic review of the research advancements related to the static and seismic properties of concrete structures of precast underground stations. The advancements in the study of the mechanical performance related to the structural joints (including wall-panel and beam-column joints) and the overall structure of the precast underground stations are discussed in detail. The research results reveal that: (1) The assembled monolithic structure and fully-assembled structure possess impressive bearing capacity, ductility, and energy absorption capabilities. These two types of precast concrete structures demonstrate excellent static and seismic properties. (2) The integrity of the assembled monolithic structure is high, which yields a seismic performance equivalent to that of the cast-in-situ structure. (3) The fully-assembled structure exhibits greater deformation capacity, with joints displaying typical semi-rigid characteristics. Based on the applications of these structures in metro systems in numerous cities in Belarus, Russia, France, and China, an overview of the application of precast structures in underground stations globally is given. Finally, the future prospects and primary research directions for precast concrete structures in underground stations are discussed. It is concluded that further research is warranted in design methodologies, efficient connection techniques, and seismic performance considerations involving soil-structure interaction.
