摘　　要：根据设计洪水分析计算、河道洪水位计算、河道冲刷淤积计算结果,结合建设项目的工程设计及施工,对河道演变趋势、河道冲淤变化及河道行洪、河势变化等进行分析,全面分析某大桥改建工程在施工期、工程运行期对河道防洪的影响,以及消除影响采取的防治措施等。文章通过对某大桥改建工程防洪影响分析,工程建设符合《防洪标准》等规程、规范要求,满足有关河道管理要求,对河道治理规划的实施影响很小。The analysis of the flood control impact of a bridge reconstruction project is mainly based on the design flood computations,the river flood level calculation,the channel erosion calculation,as well as the engineering design and construction of the project,the channel evolution trend,the channel erosion change,the flood carrying capacity,and the change of river regime,etc,The impact of the bridge reconstruction project on river flood control during the construction and operation of the project,and the control measures are analyzed.Through the analysis of the flood control impact of the bridge reconstruction project,the construction of the project meets the requirements of Flood Control Standards and the requirements of relevant river management,and has minor impact on the implementation of the river management planning.
