整体道床不用道碴和轨枕,而是由混凝土灌制,形成一个整体的结构,故而稳定性高。这对于现代铁路轨道的需要是十分有利的。铁路运营经验表明,轨道养护维修的工作量,50％以上是由于道碴层的变形所致,整体道床取消了道碴,故可大幅度地减少这项工作。根据我国铁路应用整体道床情况,整体道床轨道的养护维修工作量只有轨枕道碴道床的30～ Instead of using ballast and sleepers as a whole, the ballast beds are infused with concrete to form an integral structure and therefore have high stability. This is very favorable for the needs of modern railroad tracks. The railway operation experience shows that over 50% of the workload of track maintenance and repair is due to the deformation of the ballast layer, and ballast is eliminated on the entire ballast bed. This can be drastically reduced. According to China’s railway application of the overall track bed situation, the overall track bed maintenance workload only rail sleeper ballast bed 30 ~
