摘　　要：根据呼口大桥工程概况,阐述了经验公式法和水流数学模型法两种雍水及回水计算方法,分析确定了两种方法中参数和模型边界条件,运用两种方法计算分析呼口大桥修建与河道裁弯曲直后河道雍水高度和回水长度,通过对两种方法计算成果的对比分析,进一步分析本工程对堤防及防洪的影响,并提出相应的防洪影响评价结论和建议,为项目建设决策提供科学依据。According to the general situation of the Hukou bridge project, two kinds of calculation methods about backwater and return water： the experimental formula method and water flow mathematical model method were described to analyze the parameters and boundary model conditions of the two methods. Two methods were applied to calculate and analyze the height of backwater and the length of return water after constructing the Hukou Bridge and straightening the river course, by comparing the results of the two calculation methods, the impact of the project on dike and flood control was analyzed further and corresponding conclusion and suggestion about the flood control impact evaluation was put forward to supply scientific accordance for the decision on project construction.
