2004年小浪底水库异重流特性分析

Analysis of density current characteristic in Xiaolangdi reservoir et 2004

文章介绍黄河调水调沙试验,通过调度万家寨、三门峡、小浪底等水利枢纽工程,人工塑造异重流的方式实现了水库减淤,系统地了解水库异重流的产生条件、持续运动规律;通过调整出库流量、含沙量、泥沙粒径,使出库泥沙能够顺利排入大海。

The paper introduces the test of regulation water and regulation sand in Yellow river.The redaction of sedimentation is realized with artificial density current by way of the operation of Wanjiazai,Sanmenxia and Xiaolangdi:reservoirs for find out the producing condition and the sustaining movement law of density current in the reservoir.The sediment is flushed in the sea by way of regulating outflow,sand concentration and sand grain diameter.
