摘　　要：针对某单层地铁车站结构,建立了其三维数值计算模型,分析了其在静力、中震和大震作用下结构受力与变形,并基于现有规范对其抗震性能进行了简单评价。结果表明:1) 车站结构的柱子是其抗震的薄弱部位;2) 车站边墙与顶板和底板结合处受力较大;3) 现有的车站结构抗震性能良好,满足规范要求。论文研究成果可为类似工程的抗震设计与分析提供参考。Three-dimensional numerical simulation calculation model was established based on a practical one-layer subway station. Structure internal forces and deformation were analyzed under static load, middle seismic and large seismic wave excitations. And also, the seismic performance of the structure was evaluated according to code. The analysis results showed that: 1) The column of the subway station is a weak part during earthquake;2) The internal forces at the combination of side wall and bottom plate were bigger;3) The existing subway station has good seismic performance and can satisfy the code demands. The research conclusions in the paper can provide references for seismic design and analysis of relevant projections.
