浪店水源工程无坝引水防沙试验研究

Model Test on Liangdian Head Works (without Dam) for Checking Efficiency of Water Diversion and Sediment Control

本文主要介绍黄河小北干流浪店水源工程的动床水工模型试验成果。该项试验是研究在各种不同黄河的水沙条件下的引水能力、含沙量分布、粒径分布、各种防沙措施的拦沙效果。研究表明：浪店水源工程的取水防沙设施基本上能满足生产要求；拦沙比能达到１０％～２０％；试验并对运行管理提出了建议。

The movable bed model test for the Liangdian head works in the Xiaobei main stream of the Yellow River is introduced,the main purpose of this model test is to study the water diversion capacity,the distrbution of silt concentration and of the silt grain size,the effect of various silt preventing measures on silt checking under various water and sand condition of the Yellow River.The test result shows that the designed water diversion and silt preventing facilties can basically satisfy the requirement,the silt checking rate reach to 10% 20%.Finally,some suggestions on operation and management were presented based on the test result.
