  1. In order to increase the energy dissipation of stepped spillway at iarge unit discharge, the integhty dissipater of aerated splitter pier and steppe characteristics is studied. because of verticaj diffhaion now by aerated splitter and impachng steppe 3 by drop flow, the air concentration and the energy dissipation efficiency are greatly increased ; the potentiality of cavitations is decrease. in special at large unit discharge, this effect is more obvious

    摻氣分流墩的增加,明顯地改善了階梯面上的壓強分佈,消除或減小了階梯凹角內和立面上部的負壓;由於摻氣分流墩使水流縱向擴散以及挑流落下后在階梯上的撞擊,使水流的摻氣濃度和消能率都得到較大的提高,降低了階梯面空蝕的可能性,特別是在大單寬流量時,這種效果更為明顯。
