摘要
根据《室外排水设计规范》(GB50014-2006,2014版)、《城市暴雨强度公式编制和设计暴雨雨型确定技术导则》修订柳州市区暴雨强度公式,选定柳州国家气象站作为代表站,采用年最大值法进行降雨数据采样,采样年限为1995-2014年,挑取最大降水量的时段分为5、10、15、20、30、45、60、90、120、150、180min共11个时段。采用概率型分布指数分布曲线进行拟合调整,进行单一重现期暴雨强度公式拟合,计算重现期区间暴雨强度公式和暴雨强度总公式。
Based on specification for outdoor drainage design （GB50014-2006201-4） , urban rainstorm intensity formula preparation and guidelines for the rainstorm type determine technology＂ , rainstorm intensity formula of Liuzhou was revised and select Liuzhou country weather station as representative station, the annual maximum method is adopted for rainfall data sampling, sampling period is 1995-2014, the maximum precipitation period is divided into 11 picking times, 5, 10, 15, 20, 30, 45, 60, 90, 120, 90, 120 min. The probability distribution curve is adopted to fit the curve, and the formula of rainstorm intensity is fit for the single reproduction period, and the formula of rainstorm intensity and the total formula of the rainstorm intensity are calculated.
