中文摘要：

针对目前新疆克孜尔水库存在的泥沙淤积问题,通过动床模型试验,研究了丁坝与人工排沙渠结合的排沙效果。结果表明：①丁坝使黑孜河的入库水流偏向左岸,并携带泥沙到人工排沙渠进口附近,改变人工排沙渠的结构尺寸,可使黑孜河的入库泥沙尽可能多地进入人工排沙渠;②丁坝加人工排沙渠组合方案能更有效地达到黑孜河库段人工辅助排沙的目标,只要水库汛期来流量为每年一遇、库水位在1 135 m高程以下,就可以把黑孜河85%以上的来沙量排出库外。

英文摘要：

In view of the existing sedimentation of Kizil Reservoir in Xinjiang,the paper studied the application of spur dike and artificial sand canal combined technology in the reservoir sediment by the movable bed model test.The results show that： a） it makes the Heizi River flow deviate in the left bank through the spur dike,carrying the sediment to the entrance of artificial sand drainage and it changes the size of desilting canal to make the Heizi River inflow sediment as much as possible into artificial sand drains.b） the combination scheme of spur dike and artificial sand drains can more effectively achieve artificial desilting target in the Heizi Reservoir.As long as the reservoir flow in flood season for each encounter and reservoir water level keeps below 1 135 m,it can have more than 85% sediment of Heizi River to be discharged from the reservoir.
