公路下穿段水泥路面裂缝成因分析及处治公路下穿段水泥路面裂缝成因分析及处治 摘要:公路穿越既有铁路或公路时常采纳下穿方式,道路面层采纳水泥路面并配筋
如设计、施工不当,会造成路面裂缝病害
本文结合工程实例,分析出现裂缝病害的原因,提出处治措施,为施工实践提供有益参考
关键词:公路下穿段;水泥路面;钢筋混凝土;裂缝 Abstract:The underpass is a common type of highway traversing existing railway or highway, the pavement commonly adopts concrete pavement with reinforcing bars
If the design or construction is inadequate, the pavement crack will be produced
In the paper, by the example of a highway project, the reason of producing the pavement crack is analyzed, the disposal method is put forward, which show the other construction a helpful reference
Key words: highway underpass; concrete pavement; reinforced concrete; crack 中图分类号: TU528

与上跨方式相比,下穿方式的公路里程缩短,其引道长度仅为上跨方式引道长度的 1/3,从而节约了土地与投资
因此,公路穿越既有铁路或公
