摘　　要：芳村围排涝片是广州市荔湾区内一重要排涝片,研究其内涝模型对广州市内涝工作具有重要意义。以芳村围排涝片内8个易涝点为例,利用SWMM与GIS技术相结合构建内涝模型,每个内涝点至少用3组实测降雨-积水数据对模型进行参数率定和验证。以此为鉴,基于实测降雨数据对率定后的城市内涝积水深度模拟。结果表明,在实际降雨的情况下,模型可以准确预测出芳村围排涝片内易涝点是否会发生内涝以及内涝等级,并展示出在各易涝点内涝峰值时刻。精准的模拟效果为广州市城市内涝治理提供了重要的依据。Fangcunwei is an important drainage area in Liwan District of Guangzhou.It is of great significance to study its waterlogging model in Guangzhou.In this paper,taking 8 waterlogging prone points in the drainage area of Fangcun as examples,the waterlogging model was constructed by combining SWMM and GIS technology.At least 3 sets of measured rainfall and water accumulation data were used to rate and verify the parameters of each waterlogging point.Based on the measured rainfall data,the urban waterlogging water depth is simulated.The results show that,under the condition of actual rainfall,the model can accurately predict whether waterlogging will occur and the grade of waterlogging at the waterlogging points in the drainage section of Fangcun.And the peak time of waterlogging at each waterlogging point is also shown.The accurate simulation effect provides an important basis for urban waterlogging in Guangzhou.
