大跨度桥梁伸缩缝轨道系统研究

Research on rail system of large-span bridge expansion joint

针对目前国内外主要的大跨度铁路桥梁伸缩缝轨道系统结构及其性能的研究,结合重庆朝天门大桥的工程概况,提出一种新型的伸缩缝轨道系统结构,从而为以后的大跨度桥梁伸缩缝处轨道系统的铺设设计提供参考与借鉴。

We build jointless track by rail expansion device or small resistance fasteners on large-span bridge in our country.However,due to the expense and security of the equipment.It studies the tructure and performance of the current rail system of the large-span bridge in this paper.Combined with the project overview of the bridge of Chaotianmen,it proposes a new rail system structure for large-span bridge expansion joint to provide reference and experience for laying track system on large-span bridge expansion jiont.
