摘要
文章系统阐述了暴雨径流查算图表法和小流域推理公式法计算洪水的计算过程。对云南山区某尾矿坝流域面积内按200年及500年防洪标准分别采用暴雨径流查算图表法和小流域推理公式法进行洪水计算,通过分析计算结果得出小流域推理公式法计算结果略小于暴雨径流查算图表法。暴雨径流查算方法计算洪水过程为单峰陡涨陡落,符合云南山区性河流的洪水特性,并且考虑推理公式采用的参数是基于全国综合而定的,不一定适合该地区,另外,从防洪安全角度考虑,采用暴雨径流查算法计算的成果更为合理。
The paper systematically explains the calculation processes of flood computation using the Method of Calculation of Storm Runoff by Consulting Chart and Tab.and the Small Watershed Deductive Formula Method.For a tailings dam watershed in a mountainous area of Yunnan,flood calculations were performed according to both the 200-year and 500-year flood protection standards using the aforementioned methods.Analysis of the calculated results showed that the outcomes from the Small Watershed Deductive Formula Method were slightly lower than those obtained through the Method of Calculation of Storm Runoff by Consulting Chart and Table.The calculated flood process using the Method of Calculation of Storm Runoff by Consulting Chart and Tab.was characterized by a single peak with a sharp rise and fall,which is consistent with the flood characteristics of mountainous rivers in Yunnan.Furthermore,the parameters used in the deductive formula are based on a national synthesis and might not be suitable for that specific region.Additionally,from the perspective of flood protection safety,the results of the calculations using the Method of Calculation of Storm Runoff by Consulting Chart and Tab.are deemed more reasonable.
