对大机作业前后道床横向阻力进行了深入分析,总结出大机维修和清筛作业后道床横向阻力有较大幅度的下降,但随着线路上各种机车车辆的运行,阻力逐渐恢复的的变化规律,为以后维修作业中如何更有效地防止用轨跑道提供了一定的理论依据。
The horizontal resistance of the track bed before and after the operation of the large machine is analyzed in depth. The horizontal resistance of the track bed after the maintenance and cleaning of the large machine is greatly reduced. However, with the running of various locomotives and rolling stock on the line, the resistance gradually recovers The law of change provides a theoretical basis for how to prevent the track from being damaged more effectively in future maintenance work.
