摘要
利用杭长高速铁路某段精调作业后的检测数据,分别利用轨道质量指数和工程能力指数两种方法对轨道精调质量进行了评价及对比分析。结果表明:两种方法对于各单项的精调质量评价结果基本一致;在对各单项指标的评价及提高精调效率方面,工程能力指数方法是对现有方法的一种补充和完善;精调作业时可重点关注有较大提升空间的轨向、高低和水平三个单项,以减少后期的重复作业。
By usingthe test data of a section on HangzhouChangsha high-speed railway after the fine adjustment operation of the,two methods of the track quality index（TQI）and the engineering ability index are comparatively analyzed.The results show that the evaluations of each individual fine adjustment quality in both methods are basically the same,but for the single index evaluation and the improvement of fine adjustment efficiency,the engineering ability index method is a supplement and improvement to the existing method.The fine adjustment must focus on alignment,profile and cross-level,because they have a larger potential for improvement and reduction of the repeat works in practical operation.
