小型排涝站设计排涝流量计算方法分析

摘要

在统计分析常用的排涝流量计算方法的基础上，以广东省某小型排涝站为例，利用各种方法分别加以计算。通过对比分析，建议小型排涝站设计排涝流量，优先选用水量平衡法；其次选择平均排除法中的径流系数法和24 h暴雨洪量法；最后建立一套适合广东省的经验公式法，用于验证以上计算成果的合理性。%Based on the statistical analysis of drainage flow of common calculation method, a variety of methods are used to calculate as a small drainage station in Guangdong Province for example. Through the contrast analysis, the method of water balance is preferred for the proposed small drain-age station design drainage discharge. Secondly the mean elimination of rainstorm flood runoff coeffi-cient method and the 24 h storm flood volume method are selected. Finally a set of suitable for Guang-dong Province empirical formula method is established for the above calculation results verify rational-ity.
