摘要
无缝线路是一种新型的轨道结构,可以提高列车运行的平稳性,减少线路病害的发生,延长维修周期,在铁路建设中得到推广应用。但在小半径曲线地段铺设无缝线路,对线路的铺设和养护维修提出了更高的要求。此文针对宁芜线小半径曲线地段拟铺设无缝线路的2种强化方案,从钢轨强度和无缝线路的稳定性方面进行分析、比较和检算,提出可采用方案一铺设无缝线路。
The continuously welded rail track is a new type of track structure,which can improve the stability of train operation,reduce the occurrence of railway diseases,prolong maintenance period.And it has been widely applied in railway construction.However,the laying of continuously welded rail track in small ra- dius curve section puts forward higher requirements for laying and maintenance of track.Two strengthe- ning schemes of laying continuously welded rail track in small radius curve section of Nanjing -Wuhu railway are analyzed,compared and checked from rail strength and line stability.And it is verified that the first scheme can be used for lacing continuouslv welded rail track.
