首先，系统总结装配式地下车站混凝土结构静力性能与抗震性能的研究现状，重点对装配式地下车站混凝土结构节点（墙板节点、梁板柱节点）和整体结构的力学性能研究进展进行综述。结果表明： 1)装配整体式和全装配式2类混凝土结构均具有良好的承载力、延性和耗能能力，以及较好的静力性能与抗震性能； 2)装配整体式地下车站混凝土结构整体性强，总体抗震性能等同于现浇混凝土结构； 3)全装配式地下车站混凝土结构变形能力更强，接头具有典型的半刚性特征。然后，基于装配式地下车站混凝土结构在白俄罗斯、俄罗斯、法国和我国多座城市地铁中的应用情况，对装配式混凝土结构在国内外地下车站的应用现状进行概述。最后，对装配式地下车站混凝土结构未来的发展和主要研究方向进行展望，指出装配式地下车站混凝土结构在设计方法、高效连接方式和考虑土－结构共同工作的抗震性能等方面仍需进一步研究。
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.
