摘　　要：由于乌弄龙电站上游梯级水库未如期开发,乌弄龙水电站入库沙量较设计时明显增加,淤积床面抬高,回水淹没范围增大。为保证水库运行安全,充分发挥电站效益,结合上游梯级建设时序变化的情况,拟定不同汛期排沙水位,采用泥沙冲淤数值模型,计算各排沙水位方案的水库泥沙淤积及回水,对水库淹没范围以及发电量进行影响分析,综合比选,推荐合适的排沙运行水位,为电站建成后的运行方式提供依据。Since the upstream hydropower station of Wulonglong Hydropower is not developed as scheduled,the sediment quantity of Wulonglong Hydropower is obviously increased compared with the design results,and the backwater influenced area is enlarged with the deposited surface raising.In order to ensure the safety of reservoir operation and bring the full benefits of power stations,combined with the new sequence of the upstream hydropower station,to calculate the deposited sedimentation and backwater for the different sediment delivery water levels using the sediment deposition in the numerical model.the influence of the backwater area and the generating capacity is analyzed,with the suitable sediment delivery water level in flood season for providing the basis for the operation mode of the Wulonglong Hydropower recommended.
