无缝线路具有能减小轨道破坏量、提高旅客舒适度等很多优点,但与有缝线路相比,夏季及冬季作用着非常大的钢轨纵向力,要求特殊的轨道管理。特别是夏季的胀轨跑道事故影响面大,必须加以防止。为此,提出《无缝线路维修标准(草案)及其解释》。 Seamless track can reduce the amount of track damage and improve passenger comfort and many other advantages, but compared with the seam line, summer and winter play a very large rail longitudinal force, requiring special orbit management. In particular, the impact of the expansion rail runway accident in summer is large and must be prevented. To this end, proposed “seamless line maintenance standards (draft) and its interpretation.”
