简要介绍短缺实测资料地区中小型及部份大(二)型水利工程设计洪水计算应用的《广东省暴雨径流查算图表》的主要内容。对五个组成部份:10分钟、1小时、6小时、24小时、3天暴雨统计参数等值线图,设计暴雨定点定面关系,设计雨型——模糊聚类分析法,广东省综合单位线方法,推理公式法(1988年修订)作了扼要介绍。最后对广东省综合单位线,推理公式两种设计洪水计算方法的使用范围及成果采用原则作了说明。 This paper briefly introduces the main content of “Guangdong Provincial Storm Runoff Calculation Chart” for the calculation of design floods of medium and small-sized and some large (2) types of water conservancy project in the short of measured data area. The five component parts are as follows: contour map of heavy rainfall statistical parameters such as 10 minutes, 1 hour, 6 hours, 24 hours and 3 days, designed storm fixed point fixed surface relationship, design rain type - fuzzy clustering analysis method, Guangdong Province comprehensive Unit line method, reasoning formula method (1988 revision) made a brief introduction. Finally, the author explains the scope of application of the two design flood calculation methods in Guangdong Province and the principle of adopting the results.
