小浪底水库坝前粗泥沙排放的构想
Proposal for Discharging the Coarse sediment Deposits at the Upstream of the Dam of Xiaolangdi Reservoir
摘要
Abstract
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.关键词
