摘要
本文结合某电站上游围堰,对水工补偿收缩砼快速施工进行设计论证。内容主要包括:补偿收缩砼围堰的分缝分块,膨胀预压应力与堰体温度应力,缝面张开度的计算和防裂作用的分析,以及水工补偿收缩砼性能试验与对比选择。
This paper puts forward the design argument of the scheme of fast construction applying hydraulic shrinkage-compensating concrete for the upper coffer-wall of a station. In the paper, dealt with are mainly the following- the blocking of concrete placement of the coffer-wall, expanding prepressing stress and coffer-wall temperature stress, calculation of the opening of joints and the analysis of crack-resisting effect and the performance test and contrast choice of hydraulic shrinkage-compensating concrete.
