城市化的高度发展,导致城市防洪排涝等问题显得越来越突出,受到各级政府研究工作者的高度重视。文章以SWMM模型为基础,结合广州新白云机场实际资料,率定各有关参数,利用设计暴雨推求设计洪水,试图寻求适合中国国情的城市排水设计新方法。 The high development of urbanization has caused the problems of flood control and drainage in cities to become more and more prominent, which are highly valued by researchers at all levels of government. Based on the SWMM model and combining with the actual data of Guangzhou New Baiyun Airport, all the relevant parameters are calibrated and the design flood is deduced by design torrential rain. In this paper, a new method of urban drainage design suitable for China’s national conditions is sought.
