摘　　要：大花水水电站拦河大坝为碾压混凝土抛物线双曲拱坝+左岸重力墩,拱坝高134.50 m,由于拱坝和重力墩结构复杂,施工质量的控制是施工中的重点。根据不同部位的结构需要,采用了不同的配合比。从已浇筑的混凝土来看,所采用的配合比满足设计要求,所采取的质量管理措施对大坝施工质量控制起到了保证作用。The darn 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 structural complexity of the arch dam and gravity buttress, the quality control of the construction work must be attached to great importance. Different mix ratios are applied according to the requirement of structures at different localities. The results gained from concreting show that the mixture proved satisfactory and the quality of construction work was secured.
