泲河渡槽混凝土温度裂缝控制技术应用

Application of Concrete Temperature Crack Control Technology about Dhi River Aqueduct

通过对渡槽混凝土温度裂缝产生的原因进行分析,针对泲河渡槽C50混凝土施工,提出了降低槽身混凝土温度应力、减少混凝土表面温度裂缝产生的配合比优化、施工控制和温度监测等技术措施。工程应用结果表明,上述技术措施取得明显效果。

Though the analysis of the reasons for the crack of fluted concrete, this paper provided mix ratio optimization, construction control and temperature monitoring technical measures of reducing the temperature stress of the tank concrete and cracks in the surface temperature of concrete about C50 concrete construction in Dhi River aqueduct, the engineering application results indicated the technical measures achieved obvious results.
