摘    要:本文对南水北调总干渠与河流交叉工程进行了洪水与河床变形的平面二维数值模拟.模型采用水边界全区自动跟踪方法、考虑了交叉工程附近的局部冲刷并借助河床演变分析成果,较好地进行了特征洪水验证.通过计算给出了自然状态、设计方案时的特征洪水流场、工程附近的壅水及河床冲刷成果,根据预测分析还提出了更为合理的工程修改方案

关 键 词:交叉工程,河流模拟,水边界跟踪,局部冲刷

Abstract:A depth averaged mathematical model is applied to simulate the flood flow and the deformation of river bed for a crossing engineering is South to North Water Transfer Project of China. A procedure to treat moving boundary is adopted in this model. The model is calibrated by the data of typical flood flow.
Keywords:crossing engineering  river modeling  boundary tracking  local scour
