摘　　要：针对唐河航运工程郭滩枢纽建设对河道防洪安全影响的问题,通过水文站实测洪水资料和线性内插法计算郭滩枢纽设计洪水,根据历年实测横断面和深泓线分析河道冲淤演变和演变趋势预测,用恒定非均匀渐变流能量方程进行河道水面线计算,并应用二维模型二阶RungeKutta方法模拟计算建设工程对河道行洪时流场的影响。结果表明,唐河航运工程郭滩枢纽对河道洪水影响较小,解决了郭滩航运枢纽洪水影响评价的技术难题,可供有关部门参考。Regarding the impact of the construction of the Guotan Hub of the Tanghe Navigation Project on the flood control safety of the river channel,the design flood of Guotan Hub was calculated through measured flood data of hydrological stations and linear interpolation method.According to the measured cross sections and thalwegs over the years,the river channel scouring and silting evolution and evolution trend prediction were analyzed.The water surface profile of a river was calculated using the energy equation of a constant non-uniform gradient flow equation.The second-order RungeKutta method of a two-dimensional model was used to simulate the impact of construction projects on the flow field during river flood discharge.The results indicate that the Guotan Hub of the Tanghe Navigation Project has a relatively small impact on river flooding so that solved the technical problem of flood impact assessment for Guotan Shipping Hub,which provided reference for relevant departments.
