| 摘 要： | 泰国曼谷机场快线,全线以高架车站为主,桥上采用支撑块式无砟轨道结构。为避免简支梁与车站横梁变形不一致对轨道结构造成破坏,通过结构受力分析,设计采用一种桥接轨道板结构实现了轨道结构的连续铺设。并且说明在无砟轨道结构高度受限条件下,桥接轨道板采用钢筋混凝土结构是可行的。

| Abstract: | Thailand Bangkok airport express Line is an urban rail transit line with design speed of 160 km/h to connect SUVARNABHUMI Airport and Bangkok downtown areas. The whole line mainly uses elevated station, and double-block non-ballasted track structure is used on the viaduct. Within the range of the elevated station, a 1.2m wide station framework beam is arranged between adjacent simply-supported girders. The deformation inconsistence between the simply-supported girder and the station beam will damage the track structure, so through structural stress analysis, this paper designed a bridging track slab structure to realize continuous laying of track structure. |
