大花水水电站碾压混凝土拱坝施工工艺

Technology of Construction of RCC Arch Dam of the Dahuashui Hydropower Station

大花水水电站拦河大坝为抛物线碾压混凝土双曲拱坝+左岸重力墩,最大坝高134.50m,是目前国内在建的最高的碾压混凝土双曲拱坝。由于该拱坝体形小且结构较为复杂,因此对不同部位、不同高程的坝体采用不同的入仓方式和不同形式的模板,达到了大坝碾压混凝土快速上升的目的。

The dam of the Dahuashui hydroelectric project is a RCC double curvature arch dam with gravity buttress on the left bank with a dam height of 134.50m.Due to the small size and structural eomplexity of the arch dam, different placement and forms for concrete are applied according to the requirement of structures at different localities. As a result, the concreting work of the dam was very quick.
