摘    要:长江干线河道存在着大量的干支流交汇河段,在此交汇河段,水流运动及河床冲淤特性极其复杂,碍航问题较为严重.利用ADV对弯曲干流型汇合口水流运动特性进行模型试验性研究.研究结果表明,入汇角和汇流比是影响汇合口区域表面流速及水面比降的主要因素;入汇角的大小是决定漩涡分离区范围的主要因素之一,且随着汇流比和入汇角的增大,漩涡分离区的范围逐渐增大.

关 键 词:汇合口  概化模型试验  汇流比  入汇角

Abstract:There are a large number of confluences at the trunk line of the Yangtze River. In these confluences, flow movement and river bed scour and silting characteristics are extremely complex, and the navigation is more serious. Therefore, the ADV is used for bend type confluence to study characteristics of flow movement by model experimental research. Research results show that, the discharge ratio and the inflow angle that is between mainstream and branch are the main factors to effect characters of flow movement.The inflow angle is one of the main factors for determining the separation area of eddies, and the separation area of eddies increase gradually as the inflow angle and the discharge ratio increase.
Keywords:confluence  generalized model test  discharge ratio  inflow angle
