摘　　要：三峡水库蓄水运用以后,改变了宜昌河段的来水来沙条件,引发了河流的再造床过程。依据蓄水前后原型观测资料结合宜昌河段的来水来沙及边界条件,分析了宜昌河段的冲淤变化、深泓线、深泓纵剖面、洲滩等变化规律,并对其演变趋势做了预测。Since the impoundment of Three Gorges Reservoir,the water and sediment to the reach has changed,resulting in the process of river transformation.Based on the prototype observation data before and after the impoundment,as well as the boundary condition,this paper analyzes the river channel change,thalweg and evolution of the shoal,and predicts the trend of evolution of Yichang reach.
