摘　　要：本文建立水沙运动二维数学模型 ,通过实测水面线、流速分布及其泥沙冲淤变化过程与模型计算值进行比较 ,其值吻合较好。运用该数模计算了嘉陵江朝天门至井口河段在三峡工程运行八十年内的泥沙淤积情况并提出治理工程方案 ,预测了方案前后河段的河床演变以及港口、航道的泥沙淤积 ,选择出合理的治理方案。In this paper, variations of sediment deposition in the coming 80 years for the Jialing River at the Chaotianmen-Jingkou reach of the Jialing River, caused by the Three Gorges Project, were analysed by means of a two-dimensional water and sediment numerical model and tested through measurable water surface, flow velocity and river bed change. The river bed change and sediment deposition of that part were predicted. A reasonable project of dredging was proposed.
