摘要
本文收集了江苏省431个和山东省7个雨量站长系列资料,分析了江苏省降雨规律和暴雨特征。按照均匀分布、资料可靠一致的原则,挑选出287个雨量站进行设计暴雨分析,共分析计算了31个四级涝区、79个涝片与计算单元历年逐日面平均雨量;对各片区历年最大1、3、7天面平均雨量,进行P-Ⅲ型曲线适线,分析计算各片区不同历时5、10、20年一遇设计暴雨。
Data of 431 rainfall stations in Jiangsu province and 7 rainfall stations in Shandong Province are collected in this paper. The rainfall pattern and the rainstorm characteristics are analyzed. According to the principle of uniform distribution, reliable data consistency, 287 rainfall stations are selected for designed rainstorm analysis. 31 level four waterlogging area and 79 flood waterlogging district are analyzed. Calculation unit the daily average precipitation was calculated for each area over the years. The P- type Ⅲ curve is fitted to the maximum 1, 3 and 7 day mean rainfall in each district. Design storm of different durations of 5, 10, 20 years of each area is analyzed and calculated.
