高速铁路无砟轨道钢轨原始弯曲测试与统计分析

The original bending test and statistic analysis on high speed railway ballast-less track

采用弦线法,对高速铁路无砟轨道钢轨原始弯曲进行了现场测试,将测试数据进行数理统计分析,得出钢轨原始弯曲矢度与平方之比的平均值与标准差,为高速铁路无缝线路稳定性计算提供了参考。

This paper tested the original bending of high speed railway ballast-less track using chord line method, made statistical analysis to test data, draw the average and standard deviation to rail original curved vector and square, provided reference for the stability calculation of high- speed railway CWR.
