城市雨洪利用的设计降雨分析方法探讨

Analyzing methods of rainfall in the design of storm water harvesting in urban area

针对城区降雨径流和雨洪利用工程建设特点,提出了雨洪利用工程规划设计应采用的降雨分析方法。包括:降雨资料选择与统计分析方法,降雨时空分布和时程分配以及设计降雨过程等内容,可供城市雨洪利用工程和市政排水工程规划设计时参考。

Analyzing methods of rainfall have been introduced in the design of the storm water harvesting engineering plan and design according to the characteristics of rainfall-runoff relationship and storm water harvesting engineering construction. It includes the selection of rainfall data and statistic analysis methods, rainfall spatial and temporal distribution and its duration allocation, and design of rainfall process as well. All of them can be taken as reference in the design of storm water harvesting engineering and municipal drainage engineering plan.
