摘　　要：针对石头峡水电站初拟的溢洪道堰型泄流能力不足、水流流态较差等问题,文中对溢洪道闸室、堰型等进行了优化,并采用整体水工模型对初始设计体型、优化体型进行了试验研究。优化后溢洪道泄流能力满足设计要求,水流流态及挑流水舌形态较好。研究成果可直接应用于工程设计,为设计提供了科学依据。Aiming at the problems of inadequate discharge capacity and poor flow pattern of the spillway weir type initially proposed for Shitouxia Hydropower Station, the spillway gate chamber and weir type are optimized in this paper, and the initial design shape and optimized shape are experimentally studied by using the overall hydraulic model. After optimization, the spillway discharge capacity meets the design requirements, the flow pattern and the shape of the flow-picking tongue are better. The research results can be directly applied to engineering design and provide scientific basis for design.
