摘　　要：老鹰岩一级水库与上游龙头石水电站尾水相衔接,其水库汛期坝前运行水位将直接影响龙头石电站厂房的防洪安全。文章结合工程特点,拟定了老鹰岩一级水库的汛期运行调度方式,采用一维水沙数学模型针对各汛期排沙运行控制水位方案开展水库泥沙淤积计算及衔接回水计算,综合考虑防洪安全、库区淹没影响、发电效益等因素,推荐汛期排沙运行控制水位为903.00 m。Laoyingyan I reservoir is connected with the tailwater of the Longtoushi Hydropower Project,and the operating water level during the flood season of the Laoyingyan I reservoir will directly affect the flood control safety of the Longtoushi Hydropower Project.Combined with the characteristics of the project,the operation and regulation mode of Laoyingyan I reservoir in the flood season is formulated,and the erosion and deposition calculation and the connection backwater calculation of the proposed schemes are carried out based the one-dimensional morphodynamic model.Comprehensively considering the factors such as flood control safety,submersion effects,and the power generation benefit,the recommended water level of sediment discharge in the flood season is 903 m.
