摘　　要：无砟轨道的静态检测通常是沿着轨道线路对轨枕逐个检测,这样做虽然能够满足工程精度的需要但是工作效率较低。文中通过比较不同的插值方法的优缺点,最终选择通过三次样条插值对静态轨道检测的隔轨数据进行处理,并结合贵广高铁检测工程在采用不同的测量方案下,对高铁线路直线段和曲线段的插值结果进行分析。并且用内插后的轨检数据结果与连续测量后得到的轨检数据进行比较,得出不同条件下最有效、最准确的测量与数据处理的实施方案,工程实践证明,文中提出的检测与数据处理手段具有准确性和高效性。The static detection of unballasted tracking is the way of testing the railway sleeper one by one along rail lines, for which it can meet the needs of engineering precision but the work efficiency is low. By comparing the advantages and disadvantages of different interpolation methods, this paper selects three spline interpolations to process the data of the static orbit detection. And combing different measurement schemes of Guangzhou high-speed test engineering, this paper analyses the interpolation results of high- speed straightaways and curve segments. Comparing track inspection data resulting from continuous measurement, the paper obtains the most effective and precise measurement and data processing implementation scheme, which is proved by engineering practice.
