摘　　要：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。Overhaul of Huning line by heavy-duty machinery at night is a major technology innovation on railway construction of Shanghai Railway Administration.A preliminary assessment waw made of track condition during and after construction through numerous experiment,test,and statistical analysis of track condition quality with different construction methods,and of track reliability and track dynamic quality upon completion of construction.This provides basis for speed increase after major repair of line.
