摘要
分析了大体积混凝土温差裂缝产生的原因,通过金水沟特大桥大体积混凝土承台施工实例,从原材料选择、浇筑过程控制及混凝土的养护等方面详细阐述了裂缝的控制措施,从而避免了裂缝的产生,提高了工程质量。
The cause of large volume concrete temperature difference crack was analyzed. By the construction practice of large volume concrete raft construction of Jinshuigou supergiant Bridge, the control measurements of crack were explained in detail from choosing raw material, controlling pour process and curing concrete, so as to avoid the crack producing, and improve engineering quality.
