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。
This article mainly introduces the experimental results of the movable bed hydraulic model test of the water source project of the Little North Mainstag of the Yellow River. The experiment is to study the water diversion capacity, sediment concentration distribution, particle size distribution and sand control effect of various sand control measures in different Yellow River water and sediment conditions. The research shows that the water intake and sediment prevention facilities of Langdian Water Supply Project can basically meet the production requirements; the sediment saving ratio can reach 10% ~ 20%; and the suggestions for operation management are put forward.
