城市洪水计算方法探讨

Exploration and Discussion on Calculation Methods of Urban Flood

比较分析国内城市防洪工程中常用的推理公式法、经验公式法、以及室外排水公式法的公式基本组成、关键参数的基础上,结合一工程实例,分析了不同设计洪水洪峰流量计算方法公式的适用条件,并提出了城市小区域洪水计算过程中推荐方法选用时注意的事项。

Based on comparing and analyzing the formula composition and key parameters for the rational formula method, empirical formula method and outdoor drainage formula method often used in urban flood control projects, the different application conditions for the calculation methods under different designed flood flow are anallczed combined with an engineering example, and the matters needing attention for selecting the calculation methods used in the flood calculation of urban small catchment regions are put forward at last.
