摘　　要：通过系统水力试验 ,给出了宽尾墩附加消能的消能机理与消能过程 ,以及附加阻力系数Δζ′及其计算式。对宽尾墩改善消力池内的水流结构 ,缩短水跃长度 ,减少尾水深度 ,提高消能率及改善跃后水流状态等进行了分析 ,并给出了相应计算式。通过对比试验 ,得出了宽尾墩体型选择参数。WT5BZ]The results of serial model tests on hydraulic characteristics and optimal configurations of stilling basin with flaring gate piers (FGP) are presented in this paper. The study reveals that the FGP stilling basin can markedly enhance energy dissipation comparing with the conventional stilling basin. The formuls for calculations of drag coefficients Δ ζ′ , hydraulic jump deep tailwater h t , jump length L′ j , size of FGP as well as dissipaition rate are also provided.
