摘要
通过对兰新铁路二线双块式无砟轨道施工进行研究,从混凝土原材料、浇筑时间、抹面控制及养护方法等方面论述了控制道床裂纹产生的措施,有效的减少了戈壁地区双块式无砟轨道早期裂纹的产生。
Through the research on double block ballast-less track construction of Lan-Xin railway line 2,this paper discussed the measures to control roadbed cracks from concrete raw materials,pouring time,hand finishing control and maintenance method and other aspects,effectively reduced the early cracks caused by double block ballast-less track in Gobi area.
