摘要
以拱坝泄洪管低角度自由跌流的消能处理为研究对象，通过二元流和三元流模型试验进行分析比较，得出了考虑空气阻力系数的曲线方程及淹没条件下跃前跃后水深的关系式，提出了水力设计要点和方法．
A laboratOly study on energy dissipation of a free jet from the central outlet of an arch dam is presented. A trajectory equation of free hi and a relationship between alternate depths of hydraulic jump in a three-dimensional flow are developed. Determination of some peamcters associated with free jet and its energy dissipation below the arch dam is also emphasized.
