摘　　要：本文以双流溪大桥为例,提出了长大坡道上曲线连续梁桥上无缝线路采用常规制动与挠曲力叠加的计算方法,对《新建铁路桥上无缝线路设计暂行规定》部分计算方法及参数的合理性进行了探讨。对这类特殊桥上无缝线路的设计方法有一定的指导意义。This paper presents the calculation method for superposition of common braking and bending force on welded track on continuous beam bridge with long heavy grade and curve explores the rationalities of partial calculation methods and parameters stipulated in 《Temporary Regulation for Design of Welded Track on Newly-built Railway Bridge》 based on the example of shuangliuxi Bridge.
