摘要
介绍南昌铁路局先后尝试的3种线路单元质量评价方法。基于统计推断技术,利用大量动检、轨检数据对这3种方法进行对比分析,阐述每种方法的优缺点,建议采用基于最差单项指标的单元质量评价方法。利用南昌局管内3条线路的检测数据,应用统计学方法验证了所建议的线路单元质量评价方法的适用性。
Three evaluation methods for track unit quality used in Nanchang Railway Bureau were introduced. By statistical inference technique and a large number of track geometry data obtained from EMU （ Electric Multiple Units） inspection trains and track inspection trains, the three evaluation methods were compared, the advantages and disadvantages of each method were analyzed. The evaluation method based on the worst single index was suggested. Based on the inspection data of three railways in Nanchang Railway Bureau, the applicablility of the suggested evaluation method for track unit quality was verified by statistical method.
