基于多库优化调度的人工异重流原型试验研究

自2004年开始,黄委在小浪底水库进行大规模的人工塑造异重流排沙的原型试验,取得了宝贵的原始资料。2006年6月调水调沙运行后期,黄委防汛调度部门面对复杂的条件,利用多库联合调度和水流衔接技术,优化万家寨、三门峡、小浪底3座水库的调度运行,最终在小浪底成功塑造了人工异重流并排沙出库。此次异重流的排沙比为历次人工异重流的最大值,实际观测到的异重流过程有其独特的特点,证明了调度的科学性。

Test and Study on Multi - Reservoir - Based Optimized Regulation of Prototype Artificial Density Current

Since 2004,Yellow River Conservancy Commission has conducted large-scale prototype testing of artificial density current for sediment ejection and obtained valuable primary data.In the late period of a regulated discharge regime of the river in June 2006,the departments of flood control and regulation of YRCC successfully shaped an artificial density current in the Xiaolangdi Reservoir and ejected the sediment out of the reservoir by using the techniques of multi-reservoir joint regulation and linking up flows and optimized operation of three reservoirs of Wanjiazhai,Sanmenxia and Xiaolangdi under the complicated condition.The sediment delivery rate is the maximum of all previous artificial density currents and the actual observed process has a unique characteristic,showing a scientific regulation.The outcomes of the test have important significance of reference for the operation of sediment discharge and also have a high value on theoretical study of the Xiaolangdi Reservoir in the future.
