【摘要】 根据重庆主城三十年(1954～1983) 的原始暴雨资料, 采用“年多个样法”建立数理统计样本, 分别应用指数分布曲线和皮尔逊- Ⅲ型分布曲线, 调整样本中暴雨资料频率, 得出暴雨强度- 降雨历时- 重现期的关系, 在此基础上首次提出并运用“解析法”和“分组平均法”求解单一重现期暴雨强度公式的参数、调整各重现期暴雨强度公式的参数值,得到重庆市主城暴雨强度公式更多还原

【Abstract】 According to the original 30-year(1954-1983) storm data of Chongqing, the annual multisampling method is used to build the sample for mathematical statistics. The exponential distribution curve and Pearson -Ⅲ distribution curve are selected to regulate the frequency of rainfall in the sample, by which the distinctive relationship values of rainfall intensity, duration of rainfall and recurrence interval can be obtained. Then, the analysis method and the group average method are presented for the first time. They are used to ascertain the parameters of the storm intensity equation of single recurrence interval and regulate the parameters of the storm intensity equation of different interval.更多还原
