| 摘 要： | 铁路提速要求线路具有良好的平顺性和均匀性，轨道不平顺最大值用于紧急补修评价指标，区段的标准差用于大型养路机作业的评价指标。在现代运输条件下，要求轨道管理同时兼顾峰值和标准差。利用轨检车动态检测数据，运用统计分析方法，分析检测结果的半峰值和标准差的关系，结果表明半峰值和3倍标准差的相关性很高。

| Abstract: | It is important to keep railway track smooth and equality for railway high speed. Maximum track irregularity is the evaluate index in emergency maintenance and standard deviation of section track irregularity is the evaluate index in track maintenance machine work. With modem transportation condition, track management must consider maximum and standard deviation of irregularity. In this paper, with inspection data, the relationship between half peak and standard deviation of track irregularity is analyzed using statistic method. As a conclusion, half peak irregularity has high relativity with triplicate standard deviation of irregularity. |
