摘　　要：选择上海市杨浦区作为试验区域,对极端性天气下不同重现期和不同历时的设计面暴雨量、设计暴雨雨型进行计算。设计面雨量的计算利用研究区附近3个站点3种历时1978~2015年的降雨资料及上海市频率曲线参数的等值线图插值进行频率计算,得到各重现期的设计面暴雨量;设计暴雨雨型的计算利用江湾站2001~2015年逐分钟暴雨资料,先用模糊识别法进行雨型分类,然后用P&C法分别对单峰型和双峰型暴雨进行雨型设计,得到具有代表性的杨浦区设计暴雨雨型。In this study,Yangpu District is selected as test area to calculate design storm intensity and design storm pattern of different duration and return periods under extreme climate.The calculation of design storm intensity used rainfall data of year 1978-2015 in three nearby rain-gauges and contour map of parameters of frequency curve in Shanghai,and obtained design storm intensity of different duration and return periods.The calculation of design storm pattern used rainfall data of year 2001-2015 with interval of 5 minutes at Jiangwa Station.Fuzzy identification method was first used to classify storm into seven classes,and then PC method was used to design storm pattern with single and double peak separately.Finally,the recommended,typical and representative design storm profile of Yangpu District was presented.
