摘要
本文对含有分流的水跃方程的特性进行了讨论，提出了宽尾墩—消力池等效分流比的概念，利用安康等几个工程的试验资料给出了等效分流比和Ｅ０／ｈｋ及Ｂ′／Ｂ０的关系，讨论了宽尾墩—消力池优于平尾墩消力池的条件，并用算例表明了用等效分流比估算宽尾墩—消力池的跃后水深或选择宽尾墩的收缩比是非常方便的．
In this paper a new concept named equivalent spatial flow ratio for the flaring gate pier stilling basin is suggested. From analyzing some engineering experimental results an empirical relationship between the value of α e and the ratio E 0/h k and B′/B 0 was obtained. The numerical examples show that the simplified method proposed is very convenient for calculation.\
