Abstract
Through the spillway model establishment, the energy dissipation efficiency, aeration and flow pattern by steps with height of 0.65 m, 1.0 m and 1.3 m respectively are studied at different water level and in condition of the fixed step slope.The study presents that the ener-gy dissipation efficiency of the same step is inversely proportional with the discharge per unit width.The higher the discharge per unit width is, the weak the energy dissipation efficiency is.Regarding the different step height, the higher the step is, the higher the energy dissipation efficiency is.With increase of the aeration sills, the flow is aerated fully, the flow pattern is excellent, which can secure the safe and reliable operation of the step surface.关键词
