摘要 研究目的: 作为轨道不平顺的重要评价指标,轨道质量指数被世界各国广泛应用于铁路工务管理中。本文简要介绍了中、英、美、日、加、印、波七国的轨道质量指数计算办法,分析对比各国轨道质量指数的特点及异同。在此基础上,采用实测轨检数据研究轨道质量指数的局部波动和单项几何缺陷敏感性。
研究结论: (1)世界大多数国家采用标准差作为轨道不平顺的基础统计指标,以此基础发展的轨道质量指数计算方法略有差异;(2)与其他国家相比,我国TQI指数、波兰J指数和美国TRI指数均能敏锐捕捉局部范围内不平顺波动情况,具有较强的局部波动敏感性;(3)对于轨道综合质量指标来说,我国TQI指数和波兰J指数能够充分反映不平顺单项几何缺陷所带来的影响,具有较强的单项几何缺陷敏感性;(4)本文研究成果对指导养护维修作业、提高质量控制标准具有重要意义。

Abstract：Research purposes: Track quality index has been widely used in railways maintenance in the world, which is an important index to evaluate the status of track irregularity. The calculation methods of the track quality index of China, United Kingdom, United States, Japan, Canada, India and Poland are introduced, and the characteristics, similarities and differences of the track quality indexes of these countries are compared. With some track measured data, the sensitiveness of track quality index on local fluctuation and single irregularity defect is performed.
Research conclusions: (1) The standard deviation is chosen as the basic statistical indicator of track irregularity in most of the countries, and there is a little difference for the track quality index calculation methods in different countries. (2) Compared with the other methods, Chinese TQI index, Polish J index and American TRI index can capture the track irregularity local fluctuation, which have strong sensitivity to local fluctuation. (3) For comprehensive track quality index, Chinese TQI index and Polish J index can reflect the effect caused by single irregularity defect, which have strong sensitivity to geometry defect. (4) The research conclusions are of great significance for guiding railway maintenance and improving quality criteria.

Key words： railway track quality index track irregularity sensitiveness evaluation
