摘　　要：为分析东宝河新安大桥对河道行洪的影响,采用对工程边界拟合较好的非结构三角形网格进行数值模拟计算,对数值计算结果进行图形处理,直观的进行影响分析,最后提出工程影响防治措施。To analyse the flow in affected by Xinan Bridge in the Dongbao River,the numerical simulation calculation was carried out based on the project boundary fitted better with the non-structure triangular gridding. the graphics processing was carried out based on the numerical calculation, which can anlayse visually. Finally, the advices of treatment measure for project affections were put forward.
