摘　　要：滨江路工程对于发展城市建设和缓解交通运输具有重要意义。但是同时,它也会给河道的水流条件带来变化,从而引起河流的水安全问题、泥沙冲淤问题、航道运输问题等。本文以重庆滨江路工程和长江、嘉陵江汇流河段为对象,对滨江路给河道水流条件带来的变化进行研究,建立了两江汇流数学模型,通过计算机数值模拟,对比滨江路修建前后的河流水位和流场变化情况,阐明了引起这些变化的相关因素及其后果。Though the Flood-Control -Projects along Yantze River and Jialing River in Chongqing may well improve the urban traffic and construction, it may change the river hydrodynamic characters. There may be two consequences, one is to reduce the size of cross section and the other is to change the river shape, such as the curvature radius. The phenomena of the local backwater and velocity variety are obvious, which result in some problems for the navigation： sediment, transport and so on. In this paper, the study object is the Flood-Control-Projects and Yangtse River and Jialing River, and the aim is to study the influence of the Flood -Control-Projects on the hydrodynamic state of the two rivers. Using the numerical technique, with the two rivers hydrodynamic model the flow field＇s change of river after completion of Flood-Control-Projects is simulated and the reasons caused by the change are analyzed.
