摘　　要：曼宁公式在给水排水工程和水利工程中进行明渠水力计算时是普遍采用的计算公式.作者通过理论分析与实验证明,曼宁公式不仅适用于明渠均匀流和非均匀流的渐变流,而且在考虑壁面阻力后也适用于急变流的水力计算中.Manning formula has been widely accepted for hydraulic calculation of open channel conduits in hydraulic engineering and water and wastewater works as well. On the basis of theoretical analysis and experimental statement the author affirmed that beside for steady flow and the transition zone to unsteady flow in open channel, this formula is suitable for the hydraulic calculation of torrential current too if the resistant of the wall is taken into account.
