城市轨道交通高架车站变形缝设置的探讨

Discussion on Deformation Gap Setting for Elevated Station on Transit

规范规定混凝土现浇式框架结构伸缩缝的最大间距是55 m,城市轨道交通高架车站纵向长度一般均超过了该限值。目前国内有设缝和不设缝2种解决方法,但没有较为详细地研究论证。结合南京宁和城际轨道交通一期工程典型高架岛式车站,研究了设缝与不设缝2种车站结构布置方式,在多遇地震和罕遇地震作用及温度作用下对车站结构的受力影响差异,得出对设计有指导意义的结论,可以为业界提供一个参考。

Taking typical elevated island stations of project Phase I on Nanjing Ninghe inter-city rail transit as an example, the paper studies the two kinds of station structure arrangement with gaps and without gaps. It discuses effects in frequent earthquakes and rare earthquakes and temperature effects on station structure under different impact forces, obtaining some conclusions for guidance of future designs, which can be a reference for similar projects.
