摘　　要：目前尚无成熟的抽水蓄能电站过机泥沙确定方法。为此,研究分析了潍坊抽水蓄能电站下水库泥沙特性,开展了下水库泥沙淤积与回水计算。借鉴宝泉抽水蓄能电站过机泥沙计算方法成果,根据泥沙紊动扩散理论,在工程类比的基础上,通过对“宝泉公式”进行改进,推算求得潍坊抽水蓄能电站发生不同频率洪水时的过机含沙量。At present,there is no perfect method to determine the sediment passing through the turbine of a pumped storage power station.Therefore,the sediment characteristics of the lower reservoir of Weifang Pumped-storage Power Station are analyzed,and the sediment deposition and backwater calculation of the reservoir is carried out.Using the calculation method of sediment passing through the turbine of Baoquan Pumped-storage Power Station and the theory of sediment turbulent diffusion for reference,and on the basis of engineering analogy,the sediment passing through the turbine of Weifang Pumped-storage Power Station in different frequency floods is calculated by the improved“Baoquan Formula”.
