摘　　要：无缝线路通常是用标准长度的钢轨铺设到线路上,通过焊接成一定长度的轨条铺布在轨枕上的线路,其优点是接缝少,减少了列车对钢轨的冲击振动,列车运行更加平稳,提高了旅客舒适度,同时降低了维修成本;延长了钢轨和机车车辆的使用寿命,减轻了列车通过轨缝时产生的噪声,有利于环境保护。它是未来的发展方向,也是铁路现代化的主要内容之一。无缝线路被公认为是20世纪轨道结构最突出的改进与创新。Seamless track is a track in which many standard length steel rails are welded into considerably long rails and laid on sleepers.It has fewer joints than ordinary railway lines,less train impact vibration,smooth operation,and comfortable passengers;reduce track maintenance and repair costs;Extend the service life of steel rails and locomotives.reducing the noise caused by locomotives and vehicles impacting the track joints is beneficial for environmental protection;It is the development direction of track structure and one of the main contents of railway modernization.Seamless track is widely recognized as the most prominent improvement and innovation in track structures of the 20th century.
