为了研究淮河干流正阳关至吴家渡段河道泄流能力、河道整治工程方案及洪水调度方式等，针对河段的特点，建立了该段河道水动力数学模型，模拟了2005年和2007年洪水过程。验证计算结果表明，模型计算精度较高，可为正阳关至吴家渡段河道综合治理和行洪区优化调度等研究提供计算平台。利用该模型分析了荆山湖行洪区在2007年洪水过程中的运用效果，计算结果表明，荆山湖行洪区运用可以降低田家庵站的水位，加快了所在河段洪水汇流速度。

In order to investigate the flood discharge capacity, river regulation project and flood operation mode in the main reach of Huaihe River from Zhengyangguan to Wujiadu, a hydrodynamic numerical model was developed to simulate the flood routing based on the characteristics of this reach. This model is verified by the measured flood data in the year of 2005 and 2007. The verification results show that the model is accurate and provides a computing platform for the comprehensive treatment and optimal dispatching in flood detention areas of the main reach from Zhengyangguan to Wujiadu. The effect of the Jingshanhu flood detention area during the flood process in 2007 was analyzed by using this model. The computed results show that the use of the Jingshanhu flood detention area can reduce the water level at Tianjia'an station and increase the concentration velocity of the flood.
