Title: Analysis on the Track Quality Situation of Jiaoji Passenger Transport Line
Abstract: 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.
