地铁无砟轨道道床板混凝土裂缝成因及处理

Causes and Treatment of Concrete Cracks in Bed Plate of Subway Ballastless Track

地铁在运行过程中,如果使用的是无砟轨道道床板,能很好地保证列车的平稳运行,并且能改善列车的运行条件,使列车具有很好的使用寿命。但是,在实际运行过程中往往会出现床板裂缝现象,这会对轨道的使用寿命产生一定的影响,也对地铁的稳定正常运行产生影响,要采取科学合理的控制措施来解决裂缝问题。文章主要针对地铁无砟轨道道床混凝土裂缝问题进行了分析探讨,并提出了一些控制和修补措施,希望能为相关项目提供参考。

In the course of subway operation,if ballastless track bed is used,it can ensure the smooth operation of the train and improve the running conditions of the train,so that the train has a good service life.However,in the specific operation process,the phenomenon of bed plate cracks often appears,which will have a certain impact on the service life of the track,and also on the stable and normal operation of the subway.Therefore,scientific and reasonable control measures should be taken to solve the crack problem.This paper mainly analyzes and discusses the concrete crack problem of subway ballastless track bed,and puts forward some control and repair measures,hoping to bring help to relevant departments.
