对无缝线路伸缩区不应设置于曲线地段的探讨

Discussion on seamless line expansion area should not set on curve sections

从无缝线路受力和变形方面的研究出发,对无缝线路伸缩区在曲线地段存在问题进行了分析,证明了无缝线路伸缩区不应设置在曲线地段上,并提出解决问题的最好方法是采用跨区间无缝线路。

This paper analyses the problem that CWR’s breathing zone at the curve section about the force and distortion,and proves CWR’s breathing zone should not be set on the curve,and gives the best solution to the problem is to use CWR with welded turnout.
