摘要
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.
In this paper,two kinds of weirs,airfoir weir and hump weir,are studied by two dimensional mathematic model.Discharge coefficient curves and dynamic pressure distributions on the crest,especially the results of hydraulic characteristics of the airfoil weir,are obtained.The results show that the airfoil weir has a larger discharge capacity and there is no dangerous negative pressure along the weir profile.
