摘要
针对大体积混凝土施工中的温度监控是控制施工质量的关键。野三河特大桥主墩承台大体积混凝土通过选择冬季施工,分层浇筑,采用优化混凝土配合比设计,埋设冷却水管降低混凝土内部温度,降低混凝土内表温差等措施进行温度监控,从而有效地防治了混凝土温度裂缝,确保了施工质量。
Temperature control is the key quality of large volume concrete. In order to prevente large colume concrete cracks of Yesanhe bridge bearing base, 4 kinds of actions, such as winter construct, delamination construct, optimize concrete component design, embed cooling water pipe were taken.
