摘要:

用鎮(zhèn)江市1980—2013年連續(xù)34 a的降水觀測(cè)資料,通過(guò)數(shù)據(jù)審核處理建立暴雨統(tǒng)計(jì)樣本。對(duì)鎮(zhèn)江市近34 a的暴雨特征進(jìn)行統(tǒng)計(jì)分析,發(fā)現(xiàn)其存在較為顯著的階段性變化特征,具備開(kāi)展新一代暴雨強(qiáng)度公式研制的必要?；诖?采用年最大值法展開(kāi)修訂,基于皮爾遜III型分布確定概率曲線(xiàn)并進(jìn)行參數(shù)推求,研制了鎮(zhèn)江市新一代暴雨強(qiáng)度公式。在此基礎(chǔ)上,開(kāi)展鎮(zhèn)江市短歷時(shí)暴雨雨型設(shè)計(jì)研究。統(tǒng)計(jì)發(fā)現(xiàn):短歷時(shí)暴雨以單峰型分布為主,其雨峰位置大部分出現(xiàn)在整個(gè)暴雨過(guò)程的前半段。進(jìn)而采用芝加哥法雨型進(jìn)行雨型設(shè)計(jì),確定雨峰位置系數(shù),得到鎮(zhèn)江市短歷時(shí)暴雨的雨型設(shè)計(jì)過(guò)程,短歷時(shí)暴雨的瞬時(shí)雨強(qiáng)最高達(dá)5.9 mm/min,過(guò)程累計(jì)降水最高達(dá)105 mm。

Abstract:

Based on the precipitation data from 1980 to 2013 in Zhenjiang, the reliable rainstorm statistics sample was collected through audits of data quality. The statistical analysis on the rainstorm characteristics of Zhenjiang over recent decades found that the rainstorm obvious variation characteristics in phase exists, which is necessary to conduct the new generation rainstorm intensity formula research. The revision of rainstorm intensity formula in Zhenjiang was carried out by the annual maximum value method, the probability curves were followed by Pearson-III distribution, the formula parameters were calculated, so the new rainstorm intensity formula of Zhenjiang has been deducted. On this basis, the statistical analysis on rainfall hyetograph found that the short duration rainstorm presents unimodal distribution and the peak position appears in the first half rainstorm process. Moreover, the peak position coefficient was calculated and the rainfall hyetograph of short duration storm was designed by the Chicago hyetograph. The results showed that the maximum instantaneous rainstorm intensity can reach 5.9 mm/min and the maximum accumulated rainfall can reach 105 mm.
