摘　　要：根据面、戽水流的特征，本文利用动量定理和壁射流理论，导出了一个估算面、戽流平衡冲刷深度的新公式，并用几个工程的冲刷资料验证了公式的合理性．文中还给出了综合冲刷系数ｋｅ的推荐值．In this paper a new formula for estimating the equilibrium scour depth down stream of the bucket energy dissipator is deduced based on momentum equations and the theory of wall jets. The calculated results are verified by experimental values as well as prototype data. The recommended value of scouring coefficient Ke is given.
