近年来,短历时高强度暴雨造成的城市水灾害备受关注。提高城市暴雨强度公式计算精度,对于实现城镇发展和基础设施建设具有重要的实践意义。根据现有研究成果,目前我国仅有几十座城市拥有可供参考的暴雨强度公式,且多建立于上世纪80年代初期。2004年2月国家建设主管部门再次提出修编和补充编制,入编《给水排水设计手册》的只有上海市、济南市,浙江省、福建省补充复核修编了60余座城镇的暴雨强度公式,这些公式远远不能满足我国城市型网络化大都市
In recent years, short-term high-intensity heavy rainfall caused by urban water disaster has been of concern. It is of practical significance to improve the calculation accuracy of urban storm intensity formula for the realization of urban development and infrastructure construction. According to the existing research results, at present there are only a few dozen cities in our country that have a formula for the intensity of rainstorms that are available for reference, and most of them were established in the early 1980s. In February 2004, the State Administration of Construction again proposed the revision and supplementing compilation, and only Shanghai, Jinan, Zhejiang and Fujian Province’s supplementary manuals for reviewing the design manual for water supply and drainage revised the storm intensity formula for more than 60 cities and towns , These formulas can not meet the urban metropolis network metropolis of our country far
