暴雨强度公式是城市或地区进行雨水排水和防洪工程设计的依据。本文以郑州市1961—2010年50年的降雨资料为基础,采用年多个样法和年最大值法两种选样方法,用不同的分布函数进行重新拟合,推求郑州市城区0.25a、0.33a、0.5a、1a、2a、3a、5a、10a、20a、50a、100a等11个单一重现期暴雨强度公式和暴雨强度总公式。
Storm intensity formula is the basis of urban or regional rainwater drainage and flood control engineering design. Based on the 50 years of rainfall data from 1961 to 2010 in Zhengzhou City, this paper adopts two sampling methods, ie year multiple sample method and year maximum sample method, and re-fits them with different distribution functions to deduce the data of 0.25a, 11 single recurrence rainstorm intensity formula and rainstorm intensity formula of 0.33a, 0.5a, 1a, 2a, 3a, 5a, 10a, 20a, 50a,
