目前有砟轨道在我国高速铁路中占有重要地位，研究有砟轨道质量状态的发展对高速铁路的养护维修工作具有重要意义。从轨道不平顺指数方面对胶济客运专线的轨道检查数据进行了分析，发现单项指数中高低、轨向、水平和三角坑的影响相对较大，维修周期内轨道TQI指数在上下波动的同时逐渐增大并呈线性增长趋势，TQI指数增加到7左右时安排大机维修作业较为合理，大机维修作业后轨道TQI指数可以降低到4.5左右。%At present, ballast track occupies an important place in the high-speed railway of China. It has important significance to study the quality development of ballast track for the maintenance and repair work of high-speed railway. The track inspection data of Jiaoji passenger transport line is analyzed from the track irregularity index. It finds that the effect of the single index such as discretion, track alignment, horizontal and twist warp is bigger. TQI index of track fluctuates, at the same time it gradually increases and has a linear growth trend in the maintenance cycle. When TQI index increases to about 7, the arrangement of big machine maintenance work is more reasonable. After the big machine maintenance work, TQI index can reduce to about 4.5.
