摘　　要：根据射阳河河道特点,结合4座亲水平台分散建设的要求,采用平面二维水流数学模型,对拟建平台处的水位、流速等水力因素,利用上下游实测资料对壅水高度及流速变化进行求解和分析,为准确评价分散式亲水平台建设对河道行洪影响提供依据。According to the river characteristics of the Sheyang River,combined with the requirements of decentralized construction of four hydrophilic platforms,the plane two-dimensional flow mathematical model was adopted to solve and analyze the backwater and velocity changes of the water level,velocity and other hydraulic factors at the proposed platform by using the measured data of upstream and downstream,so as to provide the basis for accurately evaluating the impact of decentralized hydrophilic platform construction on river flood discharge.
