摘　　要：为了发挥小浪底水库的拦沙减淤作用,充分利用支流无效库容,设想结合现有的支流淤积形态及支流无效库容的分布情况,应用脉冲射流冲吸装备结合工程措施,以现有的支流作为处理库区泥沙的淤区,将库区淤积泥沙输移至两岸的支流内。可根据需要,依据泥沙的沉降特性和运动规律进行科学设计,有选择地淤积一定粒径的泥沙,排出对下游河道不产生淤积的冲泻质细颗粒泥沙,强化支流淤区的使用效率。In order to play Xiaolangdi Reservoir＇ s role in retaining sediments and reducing siltation and make full use of ineffective reservoir capac- ity of branches, it was conceived to take existing branches as silted areas for reservoir sediment, apply pulsed jet suction equipment to bring the sediment from reservoir to silted area, considering the existing siltation patterns and the distribution of ineffective reservoir capacity of branches, the engineering measures. As required, the silted areas were scientifically designed according to the sedimentation characters and movement rules of sediments to selectively deposit sediments with certain particle diameters and discharge fine particle sediments that will not silt in downstream, in order to increase the utilization efficiency of silted areas.
