摘　　要：随着高速铁路的发展,列车运行速度提高运量加大,铁道线路的各种病害也随之而来,但高速铁路却对线路结构的运行平稳性和安全性有更高的要求,这就使得轨道结构的养护维修工作变得更加困难。介绍了无砟轨道Ⅲ型轨道板灌浆孔混凝土浮起的病害问题,分析其病害成因及特点,并对灌浆孔混凝土浮起伤损带来的危害进行探究,提出了相应的预防措施及防治方法。With the development of high-speed railway,the speed of train operation increases and the capacity increases,various diseases of railway lines come along with it,but high-speed railroad has higher requirements on the smoothness and safety of line structure,which makes the maintenance and repair work of track structure more difficult.In this paper,the floating disease of the concrete in the filling holes of the typeⅢtrack plate of ballastless track is introduced,the causes and characteristics of the diseases are analyzed,and the harm caused by the floating damage of the concrete in the filling holes is briefly explored,propose preventive measures and treatment methods.
