针对目前超长混凝土结构裂缝控制的难题,通过超长结构工程设置后浇带及温度预应力技术等综合措施,充分发挥两种技术融合的优势,对后浇带进行封闭之前,张拉预应力筋,从而实现预应力效应的充分建立;后浇带完成封闭以后,结构会形成整体受力,从而解决超长结构的裂缝问题。
In view of the current problem of the crack control of the super-long concrete structure, the post-pouring zone and the temperature prestressing technology are set up by the super-long structural engineering to give full play to the advantages of the two technologies. Before the post-pouring zone is closed, Tendons in order to fully establish the prestressing effect; After the completion of the closure zone after pouring, the structure will form a whole force, thus solving the problem of long cracks in the structure.
