黔北电厂取水口枢纽布置在河道急弯段，水流流态复杂，水力学影响因素难以控制，为确保取水安全、可靠以及取水枢纽工程设计优化，通过相似原理与模型试验对特征流量级下水流流态、流速分布、泥沙冲积等关键水力因素进行研究并结合泥沙淤积结果提出了新增拦沙坎的实验条件，通过两设计方案对比取优，结果表明新设计方案泄洪防冲效果显著。鉴此，本文通过对实验设置布置、现象结果优化措施等进行详细介绍，为此类工程实验提供设计参考。
黔北電廠取水口樞紐佈置在河道急彎段，水流流態複雜，水力學影響因素難以控製，為確保取水安全、可靠以及取水樞紐工程設計優化，通過相似原理與模型試驗對特徵流量級下水流流態、流速分佈、泥沙遲積等關鍵水力因素進行研究併結閤泥沙淤積結果提齣瞭新增攔沙坎的實驗條件，通過兩設計方案對比取優，結果錶明新設計方案洩洪防遲效果顯著。鑒此，本文通過對實驗設置佈置、現象結果優化措施等進行詳細介紹，為此類工程實驗提供設計參攷。

Qianbei power plant water intake project layout in sharp bends of the river cross-section ,the flow pattern complex hydraulics factors difficult to control,to ensure the water is safe,reliable water control project and design optimization through model tests on similar principles and characteristics of the flow level under flow pattern,velocity distribution,research and other key hydraulic alluvial silt factors combined result of silta-tion,it proposed new inlet of weir experimental conditions,by comparing the two designs take priority;the re-sults show that the new design of flood and erosion control effect is significant.In view of this ,the paper set by the experimental arrangement,the phenomenon in detail,the results of the optimization measures introduced, which provides a reference for the design familiar projects.
