高低孔（坎）挑流碰撞消能的几个问题探讨

Research to SeveraI Issues of Flip and Collision Energy Dissipation of High(low) Bucket

本文依据能量守恒定理和动量方程理论，对高坝大流量高低孔浅流（坎）布置中，挑流消能碰撞点位置、碰撞角，泄流量分配、汇合流速与其方向以及入水角与其流速等问题进行探讨，以供试验初拟数据参考。

ln accordance with the law of conservation of energy and the principle ofmomentum epuation,this paper deals with the location of collision point,the collisionangle,the distribution of discharge,the velocity and direction of afflux convergence,etc.in the arrangement of high(low)bucket of high dam and large discharge,so it can betaken as for reference to the initial data of test.
