摘 要:高速铁路运行试验是高速铁路开通运营前的重要基础性工作。针对区间运行时分测试后存在大量烦琐的后续统计工作的现状,从测试样本量的特点入手,通过对区间运行时分样本的图形分析、分布函数拟合、检验,得出区间运行时分总体符合正态分布的重要结论,从而形成了区间运行时分总体均值的区间估计方法,为运行试验统计分析工作减少了庞大的工作量,取得了理想的应用效果。High-speed railway operation test is an important basic work before the railway open to operation. Aiming to the status of many continued statistic works after operation time test in high- speed railway section, starting from test amount characteristics, ,through graph analysis and distributing function combination and examination for section operation time, an important solution is achieved, which is section operation time is generally accorded with normal school, and section estimation method for general average value of section operation time is formed, which could reduce large workload for operation test statistics and analysis and achieve perfect utilization effect.
