摘　　要：新形势下新的治水思路要求在护岸工程规划设计中体现人水和谐的理念,充分发挥护岸工程的防洪、生态与经济效益。河道水力计算是衔接流域水文分析计算与水工结构设计的关键环节,对护岸工程选型、规模和造价都有着重大影响。以山区中小河流浏阳市南川河为研究区域,将流域设计洪水作为输入条件,采用MIKE11一维水动力模型进行河道水力计算,针对河道现状问题提出差异化的生态护岸工程方案,并利用模型分析工程实施后的效果。结果表明,经参数率定后的MIKE11模型可较准确地反映南川河河道水流条件,计算结果可用于指导护岸型式的选取及设计参数的确定,据此制定的生态护岸工程方案可起到固坡护岸、强化河道行洪安全、稳定河势和改善河道生态状况的效果。Under the new situation,the new idea of water management requires the reflection of human-water harmony concept in the planning and design of revetment projects,which can help yield the greatest comprehensive benefits of flood control,ecology and economy.River hydraulic calculation is the key link between watershed hydrological analysis and hydraulic structure design,and has a significant impact on the selection of revetment type,project scale and cost.Taking the typical small and medium mountain rivers,namely the Nanchuan River in Liuyang City as the study area,this paper uses the MIKE11 one-dimensional hydrodynamic model for hydraulic calculation based on the designed basin flood inputs,and puts forward differentiated ecological revetment project schemes aiming to solve different problems,and then analyzes the effects of revetment projects.The results show that the MIKE11 model after parameter calibration can accurately simulate the flow regimes of the Nanchuan River,and the calculation results can help to guide the selection of revetment type and determination of the related design parameters.The ecological revetment project schemes formulated based on the model results can help to consolidate the bank slopes,promote the flood propagation,stabilize the river regimes and improve the channel ecological conditions.
