摘　　要：通过建立长江中游牯牛沙水道二维水沙数学模型,考虑三峡水库运用后该河段的来水来沙情况的新变化,分别对牯牛沙水道航道整治工程的整体工程效果和一期工程效果进行了计算分析及比较,为该河段航道整治方案的最终确立及航道整治工程效果的合理预测提供了依据。Based on the establishment of a 2-D flow and sediment numerical model for Guniusha Water Way of the middle reach of the Yangtze River,the new status of the inflow and sediment of the river reach after the operation of the Three Gorges Reservoir is considered herein;in which both the effect of the whole project and the effect of the Phase I Project for the project of navigation channel regulation for Guniusha Water Way of the middle reach of the Yangtze River are analyzed and compared respectively,and then a reliable basis is provided for not only the reasonable anticipation of the effect of the navigation channel regulation project,but also for the final confirmation of the regulation scheme of the water way.
