斜拉桥大体积承台裂缝产生的机理及温控技术

Mechanism and Temperature Control Technology of Crack Formation in Large Volume Bearing Platform of Cable-Stayed Bridge

在斜拉桥建设施工中,大体积承台是非常典型的结构。由于承台结构的混凝土原材料性质,在建设施工过程中产生裂缝是比较常见的一种现象,且在一定程度上是不可避免的。为了更好地解决裂缝问题,本文对裂缝产生的机理进行深入研究和分析,并通过运用温控技术达到控制裂缝产生的目的。

In the construction of cable-stayed bridge,large volume bearing platform is one of the typical structures.Due to the properties of concrete raw materials of the bearing platform,cracks are a common phenomenon in construction and also unavoidable to some extent.In order to better solve the crack problem,it is necessary to study and analyze the mechanism of crack formation in depth,and achieve the purpose of controlling crack formation through temperature control technology.
