摘    要:为适应沿江城市发展,对冲积平原河流的河漫滩地进行了堤线改线。采用平面二维水流泥沙数学型进行堤线改线影响计算,模型考虑了悬移质及推移质泥沙运动,桥渡及料场的阻力变化,应用模型计算了赣江南昌河段喻家湾堤线改线工程前后的洪水水位壅高,断面流速分布变化,取土料场回淤情况,并对改线工程进行了评价。

关 键 词:冲积河流 堤线改线 泥沙 数学模型

Abstract:With the development of urbanization,a part of flood plain is used for urban districts with the engineering of riverside embank-ment change.The2-D flow and sediment mathematical model is used to compute the effect of the engineering of riverside embankment change.Sediment transport includes suspend load and bed load.The variation of flow friction with bridge and river dredging has been considered.The model has been applied to Nanchang reach in Ganjiang River.The change of water level,cross section velocity and deposition of dredging have been computed.
Keywords:alluvial river  riverside embankment change  sediment mathematical model  computation
