( 6 ) 3d integer model of spillway and frusta of brake are established and numerical computation of 3d viscous flow over spillway is completed. the influence of frusta of brake for design parameters such as shape of free surface, pressure on dam, flux coefficient is computed aim at type of frusta of brake and disposal on dam and compute result of different type of frusta and disposal model is compared
6 ）通過建立溢流壩和閘墩的三維整體模型，完成了對三維過壩水流粘流場的數值計算，針對閘墩的型式及在壩面的布置計算了閘墩對水面線形狀、壩面壓力、流量系數等設計參數的影響，並將不同墩型與布置形式的計算結果進行比較。 -
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。
