摘　　要：镇安抽水蓄能电站采用水库淤积一维数学模型,考虑抽放水状况的水库泥沙淤积过程,计算不同运行年限抽放水过程的过机含沙量以及颗粒组成,计算成果表明过机含沙量无法满足抽水蓄能电站的要求。因此,采用设置工程防排沙措施——下水库拦沙坝,实现抽水蓄能电站对调节库容、过机含沙量的要求,较好地解决镇安抽水蓄能电站的泥沙问题。By application of on one-dimensional mathematical model for the reservoir sedimentation and in consideration of the sedimentation accumulating course during water pumped and discharged for Zhen＇an Pumped Storage Power Plant, sediment concentration and particle com- position through the unit during water pumped and discharged in different service life are analyzed and calculated. The study results present that the sediment concentration through the unit cannot meet the requirements of the pumped storage power plant. Therefore, the engineering measure, namely, construction of sand-preventing dam in the lower reservoir, is applied to meet the requirements of the plant on the active reservoir capacity and sediment concentration through the unit. Application of this measure solves the sediment problem of Zhen＇an Pumped Storage Power Plant well.
