摘　　要：龚嘴、铜街子两水库原始库容淤积达60%以上,影响了水电站的安全运行和水库调节性能的发挥。为此,对大渡河梯级水电站来沙组成以及上游调节水库瀑布沟投产后,龚嘴和铜街子水库入库泥沙变化情况进行了分析计算,提出了利用弃水造峰的梯级水库水沙联合调度方案,并通过水库冲淤数学模型进行减淤效果对比分析。结果表明,通过瀑布沟、龚嘴和铜街子三座水库水位和流量的合理控制,可有效减少龚嘴和铜街子水库泥沙淤积。More than 60% of original storage in Gongzui Reservoir and Tongjiezi Reservoir in Dadu River are seriously deposited by sediment. The sediment not only affects the safe operation of hydropower stations, but also affects the adjustment performance of reservoirs. The changes of sediment inflow in two reservoirs are calculated after the operation of Pubugou Reservoir which is a regulator in upstream basin. The water and sediment joint scheduling of above three reservoirs are proposed by utilizing surplus water to form artificial flow peak, and the sediment reductions of Gongzui and Tongjiezi reservoirs are compared by mathematical model. The results show that the sedimentation in Gongzui and Tongjiezi reservoirs can be effectively mitigated by controlling water head and flow of three reservoirs.
