中文摘要: 设计了一种新的暴雨强度公式及其设计雨型的样本采样方法:强降水自然滑动取样,并采用重庆沙坪坝国家基本站1961—2016年逐分钟降水资料,按照城市暴雨强度公式编制和设计暴雨雨型确定技术导则规定的选样方法,对重现期、年最大值、自然场次取样和强降水自然滑动取样进行了分析比较。分析结果认为:强降水自然滑动取样具有流程简洁、样本代表性更高的优点。为今后编制暴雨强度公式和设计雨型的取样方法提供新的思路。
Abstract:A new sampling method for storm pattern samples: precipitation natural sliding sampling was designed in this paper. According to this sampling method which is used in the urban rainstorm intensity formula and the design technique for determining rainstorm pattern, the four sampling methods—return period sampling, annual maximum sampling, natural field sampling and precipitation natural sliding sampling, are analyzed and compared by using the minute precipitation data at the Shapingba National Basic Station of Chongqing from 1961 to 2016. The results showed that precipitation natural sliding sampling has the advantages of simple flow and higher sample representation. This method can provide a new reference for formulating rainstorm intensity formula and designing rain pattern sampling in future.
