单轨"T"型独柱墩高架车站结构设计若干问题探讨

研究目的:单轨交通系统在国内系首次采用,通过对规范的选用、站台雨棚结构、结构计算简图、位移与挠度限值的确定、结构整体动力特性等若干结构问题的探讨,可供制定相关规范规程时借鉴、参考。研究方法:结合国内首次采用跨座式单轨交通方式的重庆轻轨较新线高架车站工程实例,进行研究探讨。研究结果:提出高架车站的分析计算方法、构造要求、位移与挠度限值及旅客舒适度要求等。研究结论:高架车站需同时满足建筑结构设计规范和铁路桥涵设计规范;站台雨棚宜采用轻钢结构;“T”型独柱墩高架车站应进行结构整体动力特性分析。

Discussion about Structural Design of Monorail Elevated Station Built on T-type Single Column Pier

Research purposes: Monorail transit system was adopted first in China.The discussion about the selection of specifications,structure of platform shed,structural calculation diagram,determination of displacement and deflection limiting values,and integral dynamic behavior of structure can be used for reference for establishment of relevant specifications and regulations.Research methods:The discussion is carried out in combination with elevated station on Jiaoxin Line of Chongqing Light Rail Transit which is a straddle-type monorail traffic mode adopted first in China.Research results:This paper puts forward the analysis and calculation methods,structural requirements,displacement and deflection value and passenger comfort requirements for elevated station.Research conclusions:The elevated station need satisfy not only "Code for structural design of building",but also "Code for design of railway bridge and culvert".The light steel structure should be adopted for platform shed.The analysis on integral dynamic behavior of structure of station built on T-type single column pier should be carried out.
