高坝闸门不同位置闸孔恒定自由出流流量系数

Discharge Coefficients for Steady Free Flow under Gtates on Crest and on Position Lower than Crest of High Dam Spillway

对闸门在堰面位置不同对流量系数的影响进行了研究，在模型实验基础上，分析、拟合出两种不同情况下流量系数的经验公式，用测定两种情况下坝面压强分布的方法对经验公式进行了分析．

This paper treats experimental study on discharge coefficients for steady free flow under gates on the crest and on the position 0. 4Hd lower than on the crest of the spillway with creager-officerob profile. On the basis of experimental data two formulas of discharge coefficients are developed respectively for the above gate position.
