摘要
结合重庆朝天门长江大桥主墩横梁C50混凝土一次浇筑3 447m3的施工实践,从混凝土配合比设计、施工工艺、温度控制等方面,对高标号大体积混凝土的施工技术进行总结,可为同类施工提供参考。
Combining with the construction practice of the main pier′s transverse beam in Chongqing Chaotianmen Bridge, in which 3 447m^3 C50 concrete has been cast oneoff, summarization on the con struction technology of highstrength and major volume concrete from the proportion design, construction technics, temperature control can offer the reference for similar project.
