铁路轨道在列车重复动荷载作用下产生各部分的变位和变形称为轨道偏差。轨道偏差对列车安全运行、旅客舒适度及轨道部件伤损等有很大影响,因此必须对轨道偏差、列车振动及轨道部件进行综合管理。下面介绍日本既有线及新干线轨道变形整修标准,这对修订制订我国铁路轨道养护标准必有参考价值。 Railway track in the train under repeated dynamic load caused by changes in the various parts and deformation known as the track deviation. Track deviation on the safe operation of the train, passenger comfort and rail components have a significant impact on injury, it must track deviation, train vibration and track components for integrated management. The following introduces Japan’s existing line and the Shinkansen rail deformation renovation standards, which revised the development of China’s railway track maintenance standards must have reference value.
