公路和桥梁混凝土的施工温度和裂缝防治措施

Construction Temperature and Crack Prevention Measures of Highway and Bridge Concrete

阐述了公路和桥梁工程中混凝土结构温度应力裂缝的产生机理,提出了混凝土结构裂缝的防治措施,包括优化混凝土配合比,选取合适的原材料;合理控制施工阶段和养护结构的温度等。从而减少公路和桥梁工程混凝土结构裂缝,提高工程施工质量。

This paper expounds themechanismof temperature stress crack of concrete structure in highway and bridge engineering,and puts forward the prevention measures of concrete structure crack,including optimizing concrete mix ratio and selecting suitable raw materials,reasonable control of construction stage and maintenance structure temperature.Thus,the cracks of concrete structures in highway and bridge engineering can be reduced and the construction quality can be improved.
