摘    要:运用重庆河段平面二维泥沙数学模型对三峡水库蓄水方案改变后重庆河段水流运动及泥沙冲淤进行模拟.文中给出了数学模型的计算条件、关键问题的处理方法及详细验证结果,并运用此模型计算分析了三峡水库采用新的蓄水方案后重庆河段在100年内的冲淤变化情况,结果表明:模型验证结果良好,具有较强实用性;新的蓄水方案情况下,重庆河段在三峡水库蓄水后淤积量逐年增长,泥沙淤积纵向分布主要集中宽阔的浅滩段,横向分布主要集中在汛期的回流区或边滩部位,部分浅滩河段随着三峡水库运用时间的增长出现碍航问题.

关 键 词:三峡水库  重庆河段  航道  数学模型

Abstract:Based on the two-dimensional unsteady flow and nonuniform sediment mathematical model,flow movement and river bed deformation of Chongqing reach are simulated.The deposition and erosion of Chongqing reach during the Three Gorges Reservoir has been impounded are researched with the model.And a conclusion is drawn that the model is reliable and applicable;the deposition amount increases with the Three Gorges Reservoir operating;the shoals,backflow region and over bank are the main deposited area;there will be navigationobstruction in the shoals.
Keywords:Three Gorges Reservoir  Chongqing reach  navigation channel  mathematical model
