摘　　要：为给武汉河段道湖口地区吹填造地的采沙工程提供依据,本文建立了武汉河段二维水沙数学模型,对实施采沙工程后该河段的水位变化及河道回淤情况进行了计算,并对模型计算结果进行了合理性和实测资料验证分析。结果表明:模型计算合理、可靠。In order to ensure the safety of embankments Daohukou region for Wuhan, planning to fill in the areas of Daohukou region, we build the project. This paper argues gathering sand on the fiver in Wuhan river stability, flood control security in the region. The establishment of a two-dimensional mathematical model of water and sediment, which calculates and analyses the river＇s flow, water level changes, siltation in the river case alter the river sand mining project. And the model has been calibrated and confirmed by field data. Computational result shows that the model calculation is rational and reliable.
