摘　　要：暴雨是造成城市内涝的主要原因之一,但暴雨的雨型是随机出现且多样的。为了对内涝采取精确的控制措施,需要结合城市排水设施的运行需求,对暴雨的雨型进行分类研究。研究总结了国内外雨型分类的研究,并对广州市东濠涌流域进行在线雨量监测,以2场实测降雨为例,对实测降雨使用标准化欧氏距离、相似度分析方法进行模糊识别。研究结果显示,本雨型模糊识别方法能够较好地根据4场实测降雨的短时降雨对正在发生的降雨雨型进行分类判定。研究成果可基于实时监测并动态模糊识别的雨型进行排水系统动态调度。Heavy rainfall is one of the main causes of urban flooding,but the rainfall patterns of heavy rainfall are random and diverse.In order to take precise control measures for waterlogging,it is necessary to classify and study the rain patterns of heavy rainfall in conjunction with the operational requirements of urban drainage facilities.In this study,we summarize the domestic and international research on rain type classification and conduct online rainfall monitoring on the Donghao Chung watershed in Guangzhou city,and fuzzy identification of the measured rainfall using standardized Euclidean distance and similarity analysis methods for the measured rainfall with two measured rainfall events.The research results show that the present rainfall fuzzy identification method can better classify the ongoing rainfall patterns based on the short-time rainfall of the four measured rainfall events.The research results can be used for the dynamic scheduling of drainage system based on the real-time monitoring and dynamic fuzzy recognition of rain patterns.
