摘　　要：根据三峡成库前后实测地形、水位、流速流向资料,并结合平面二维数学模型成果,分析了常年库区急弯分汊型河道皇华城河段三峡蓄水后水流结构及水流要素等特征值的变化及淤积对航道的影响,总结了皇华城河段的淤积规律,提出常年库区河段都将面临河型转化。According to the information of terrain,water level,flow velocity and direction after and before impoundment of the Three-Gorges reservoir,we analyze the changing of the flow structure,hydraulic factors by the mathematical model for 2-dimendion flow,and channel condition,we also summarize the sediment regulation of the sharp bend and braided reach,Huanghuacheng reach,and conclude that such reaches can all be confronted with transforming of channel pattern.

关 键 词：三峡工程 水库淤积 航道条件 河型转化
