浅谈引气剂在严寒地区无砟轨道支承层的应用

Application of air entraining agent in supporting layer of ballastless track in severe cold area

近年来,高速铁路发展迅猛,无砟轨道以其特有优势被广泛应用于中国各大地区,其中支承层作为重要组成部分,相关的技术研究尤为关键。主要对严寒地区无砟轨道支承层现存的问题及研究现状进行分析,并研究引气剂对支承层混凝土相关性能的影响。

In recent years,with the rapid development of high-speed railway,ballastless track is widely used in major regions of China with its unique advantages,in which the supporting layer is an important part,and the relevant technical research is particularly key.This paper mainly analyzes the existing problems and research status of ballastless track support layer in severe cold area,and studies the influence of air entraining agent on the relevant properties of support layer concrete.
