根据三川流域的3个雨量站记录的逐日降雨资料及锦绣川水库入库量资料,采用相关性分析法分析三川流域上游的降雨与锦绣川水库入库量的关系,得出降雨与入库量之间存在着相关性。通过收集和分析该流域降雨资料,利用P-Ⅲ曲线推求设计暴雨;运用同频率放大倍比法,推求出100年一遇的设计暴雨过程线,并与单位线相结合求出设计入库洪水量过程线。进而,分析评价了降雨资料以及利用的意义,对三川流域内设计暴雨、水库防洪泄洪预警具有重要价值。
Based on the daily rainfall data recorded at three rainfall stations in Sanchuan River basin and the storage amount of Jinxiuchuan Reservoir, the correlation analysis was used to analyze the relationship between the rainfall in the upper reaches of Sanchuan River and the storage amount of Jinxiuchuan Reservoir, There is a correlation between them. By collecting and analyzing the rainfall data of the basin and using the P-Ⅲ curve to infer the design torrential rain, using the same frequency multiplying ratio method, the 100-year design rainstorm process line is deduced and combined with the unit line to determine the design storage Flood process line. Furthermore, analyzing and evaluating the significance of rainfall data and its utilization is of great value to the design of heavy rain and reservoir flood control and flood warning in the Sanchuan River Basin.
