摘　　要：井流消能是一种结构简单、造价低廉、且消能效果甚优的新型消能方式．在井流流态中，超典型井流又因其消能效果最好而在低坝消能中具有很大的推广应用价值．本文通过试验研究，探明了超典型井流的流态特性及其演变规律，得出了可供设计应用的计算方法和计算公式．本成果已在三十余座低坝工程中得到应用，并取得良好的工程效益．Well-flow energy dissipation is a new method,and it is simple in structure, low incost and high in efficiency. According to its good energy dissipation effect for low dams, thesuper-typical well-flow is of practical value and it should be popularized. The flow and evolution characteristics of super-typical well-flow have been analyzed. The equations for designhave also been presented. The research results have been applied to over 30 low dam projects. And engineering benefits have been achieved.
