In order to study the characteristics of the stepped spillway overflow comprehensively and seek for the measure to increase the energy dissipation of the stepped spillway at large unit discharge, the method of turbulence numerical simulation and model test are used to study the stepped spillway overflow. in view of the curved free water surface, complicated boundary condition and turbulence flow, it very difficult to simulate the stepped spillway overflow
為了對階梯溢流壩面流場特性進行全面的研究，同時探求在大單寬流量下提高階梯溢流壩消能率的措施，本文採用紊流數值模擬與實驗相結合，數值計算為主、實驗為輔的研究方法對階梯溢流壩面流場進行了較系統深入的研究。
