摘要
为揭示高坝泄洪消能机理及水垫塘防护措施 ,系统地研究了水垫塘内的流态特征 .根据高坝下游水垫深度的不同 ,塘内水流呈现自由冲击射流、淹没冲击射流和面流三种流型 .结合二滩、小湾等工程试验资料 ,本文给出了不同流态之间转变的实用判别条件 .
A systematic study on flow patterns in plunge pools down stream of the high dams is carried out to investigate the mechanism of the energy dissipation.It is found that three patterns may occur to the flow in the pool including free impact jet,submerge impact jet and surface flow according to the downstream water level.The criteria for determining the flow pattern are proposed.
