摘　　要：市域(郊)铁路中高架车站的建设数量不断增长,而国内对其抗震性能的研究尚未成熟,基于此文章旨在探究地震力作用下市域(郊)铁路高架车站的抗震性能。首先,对地震动特性进行研究,采用反应谱和地震加速度时程分析方法分别模拟地震力;其次,建立数值模型进行地震响应分析,进行高架车站的结构计算;最后,根据相关规范要求,评估高架车站关键构件的抗震性能。结果表明,在多遇和罕遇地震下,“建桥合一”形式高架车站的各类抗震性能验算满足相关规范要求,对后续同类型高架车站的抗震设计具有一定借鉴意义。The construction of elevated stations in urban region(suburban)railways is continuously increasing,but there is still limited domestic research on their seismic resistance performance.This article investigates the seismic resistance performance of elevated stations in urban region(suburban)railways when subjected to earthquake forces.Firstly,seismic characteristics are examined by simulating earthquake forces using response spectrum and seismic acceleration time history analysis methods.Secondly,a numerical model is established for seismic response analysis and structural calculations of elevated stations.Finally,based on relevant specifications,the seismic resistance performance of key components of elevated stations is evaluated.The results indicate that,in the face of frequent and rare earthquakes,various types of seismic resistance performance calculations for"integrated bridge and construction"type elevated stations meet the requirements of relevant specifications,offering valuable insights for the seismic design of similar elevated stations in the future.
