摘　　要：根据天然河段的地形条件,结合某港口建筑物布置,构建了工程河段流场数值计算模型.基于标准k-ε紊流模型,用有限体积法离散控制方程组,利用全隐式多重网格耦合求解技术,预测了港口工程河段水流流场的变化.Based on the complex geometrical condition of a natural river and the design scheme of a port project, a 3-D numerical simulation model for the project reach is developed. The control equation group is discretized by adapting the finite volume method, and the variation of the flow field of the project reach is predicted by using the coupled multigrid with full implicit scheme.
