摘　　要：采用标准k-ε模型模拟湍流,利用VOF法追踪自由水面,对阿拉沟溢洪道在不同流量下进行三维流场数值模拟,并将设计洪水位和校核洪水位两种工况下溢洪道的自由水面、底板压强、断面流速与模型试验观测数据进行对比分析。结果表明:数值模拟和模型试验资料基本吻合,为阿拉沟水库溢洪道优化设计提供更为可靠的依据。By using the standard k - ε model to simulate turbulence and VOF method to track the free surface of Alagou spillway at different flow rates of three-dimensional flow field numerical simulation. And the design flood level and check flood level under two kinds of conditions, the free water surface and bottom pressure, velocity and the model test observation data were compared and analyzed; the results show that the numerical simulation results and measured data are basically consistent, witch can provide the reliable basis for Alagou reservoir spillway optimization design.
