摘　　要：针对我国编制城市暴雨强度公式工作中存在的问题,介绍了城市暴雨强度公式推求过程中频率分析计算时皮尔逊Ⅲ型分布的适线原则和方法。以广州市实际工程为例,根据广州市中心城区深层隧道排水系统规划设计工程上的要求,将广州市52年实测年最大值样本系列分别进行短历时和长历时下的皮尔逊Ⅲ型理论曲线的频率适线分析,并将长、短历时下的适线结果进行了分析论证。To solve the problem existing in the preparation of urban storm water intensity formula, the principles and methods about fitting curve of Pearson type Ⅲ in urban storm water inten- sity equation deduction were introduced. In an actual project in Guangzhou, according to the requirement of deep tunnel drainage system planning and design projects in Guangzhou center, the measured annual maximum sample series in 52 years data of Guangzhou was analyzed by fitting curve of Pearson type Ⅲ in short duration and long during; in addition, the fitting results were analyzed and and demonstrated.
