摘　　要：随着城市轨道交通建设的快速发展,高架线路的增长比例更快。如何在高架车站的结构选型和设计方面取得优势,将高架车站对城市空间的影响降到最低成为亟待解决的问题。目前,城市轨道交通高架车站纵向长度均较长,超过规范规定的现浇混凝土框架结构设缝的最大间距要求。结合郑州市轨道交通线南四环至郑州南站城郊铁路工程,通过对140m高架车站设置温度缝与不设置温度缝建立两种模型,分别对车站框架主梁裂缝、结构配筋的影响结果进行对比分析,从工程安全及造价等方面研究了高架车站设置温度缝的合理性及必要性,得出对设计有指导意义的结论。With the rapid development of urban rail transit construction,the growth rate of elevated lines is faster.How to obtain advantages in structure selection and design of elevated station and minimize the impact of elevated station on urban space has become an urgent problem to be solved.At present,the longitudinal length of the elevated station of urban rail transit is longer than the maximum spacing requirement of the cast-in-situ concrete frame structure joints specified in the code.This paper studies the suburban railway project of Zhengzhou rail transit line from Southern Fourth Ring to Zhengzhou South Station.By establishing two models with and without temperature joints at 140 m elevated station,the effects of cracks in main girder of station frame and structural reinforcement are compared and analyzed.The rationality and necessity of setting temperature joints in elevated station are studied from aspects of engineering safety and cost,and conclusions of guiding significance for design are drawn.
