摘要
针对城市轨道交通特大跨钢桥轨道结构选型问题,结合国内外特大跨钢桥轨道应用情况,分析了特大跨钢桥对轨道结构的特殊要求,并对有砟轨道和无砟轨道应用于特大跨钢桥上的适用性进行比较。以重庆环线鹅公岩大桥轨道专用桥为例,分析了有砟轨道和减振垫浮置板无砟轨道在钢桥上应用的影响因素。通过比较得出特大跨钢桥适宜采用无砟轨道型式的结论。
The paper focuses on the track structure selection of extra-large span steel bridge of urban rail transit.Based on the investigation of the track structure of extra-large span steel bridge in both China and overseas countries,it analyzes the special requirements for track structure of extra-large span steel bridge and makes a the applicability comparison of ballast track and non-ballast track for extra-large span steel bridge.Taking E' gongyan Rail Bridge of Chongqing Rail Transit Loop Line as an example,it analyzes the factors which influence the application of ballast track and vibration absorbing pad floating slab non-ballast track on steel bridge.Through comparison,it comes to the conclusion that non-ballast track is more suitable for extra-large span steel bridge.
