circular weir

The hydraulic experiment for flowing ability of arc weir was conducted to use the over-flow earth-rock dam,comparing with a series of test results.

对于在过水土石坝上设置圆弧曲线堰后的过流能力进行了试验研究,根据几组圆弧曲线堰过流能力的比较,初步分析了圆弧曲线堰的流量系数变化规律及圆弧半径等对其的影响。

Discharge coefficient curves and dynamic pressure distributions on the crest,especially the results of hydraulic characteristics of the airfoil weir,are obtained.

对可能作河岸明流溢洪道控制堰的翼形堰和驼峰堰进行了二维流场的数学模型研究，求得了各堰型的流量系数和堰面动水压强；定量给出了各堰型特别是翼形堰的泄流能力变化规律和压强分布规律及主要影响因素。
