摘　　要：为了耦合水工构筑物(堰,坝等)与山区河流平面二维流场,基于三角形网格有限体积法,建立一个将水工构筑物作为内边界条件的平面二维洪水演进模型,并利用好溪江梯级电站河道段的地形和水文监测资料对此模型进行验证.模拟结果表明:该模型可以有效模拟水工构筑物的过流,具有良好看数值稳定性和计算精度.A model was developed, which coupled hydraulic structures and two-dimensional flow filed to do numerical simulations. It took hydraulic structures as inner boundary conditions and used the finite volume method to simulate 2D flow field based on 2D triangular mesh system. This model was applied to a real case of Haoxi River with cascade hydropower stations to test computational stability and accuracy. The simulation results indicate that this model can effectively stmulate overcurrent of hydraulic structures with good numerical stability and accuracy.
