整体浇筑长大混凝土结构早期开裂问题探讨

Discussion on the early cracking of whole-casting and large-scale concrete structure

整体浇筑、运输、拼装已经成为长大结构重要的施工方法之一,但结构的早期开裂问题也日益凸现。结合工程实例进行了详细的理论计算,对整体浇筑长大结构的施工具有一定的指导意义。

whole-casting, transportation and making up have become one of important methods of large-scale structure. However, the problem of cracking in early stage has become serious. Here detailed calculation has been taken with actual engineering, which will be significant for the construction of large-scale structure with one piece casting.
