摘　　要：中小型水库工程中,一般不专门开展水工模型实验。溢洪道的水力设计主要依赖于水力学计算,故水力计算的清晰、严谨至关重要。结合金足水库溢洪道工程,阐明、梳理了溢洪道水力设计的要点及计算方法,确保溢洪道具有良好的水力体型。In small and medium-sized reservoir engineering,hydraulic model experiment is not specially carried out.The hydraulic design of spillway mainly depends on hydraulic calculation,so the clarity and preciseness of hydraulic calculation are very important.Combined with the spillway project of Jinzu reservoir,this paper expounds the main points and calculation methods of the spillway hydraulic design,so as to ensure that the spillway props have good hydraulic shape.
