沪宁线大型养路机械夜间线路综合施工是上海铁路局线路施工技术的重大改革。通过对不同施工手段、作业方法下轨道状态质量 ,大型养路机械作业后轨道稳定性 ,轨道动态质量进行大量的试验、测试、统计分析 ,对施工中、施工后的轨道状态质量作出了初步评价 ,为施工后慢行速度的提高提供参考依据。
The comprehensive construction of Shanghai-Nanjing Line large-scale maintenance machinery night line is a major reform of the construction technology of the line of Shanghai Railway Administration. Through a large number of tests, tests and statistical analysis on the different construction methods, the quality of the track under the operation method, the track stability after the operation of the large track maintenance machinery and the dynamic quality of the track, preliminary evaluation is made on the track condition quality during construction and after construction, Provide a reference for improving the creeping speed after construction.
