摘要
做好城市排水的前提是要对城市暴雨的情况和规律有清楚的认识和研究,暴雨强度公式是城市雨水排水系统规划与设计的重要依据。通过一个具体算例,结合新乡市暴雨强度公式,提出两个独立排水流域雨水径流的分析方法,包括降雨历时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。
The premise of better urban drainage should be clearly to cognize and study the situation and law of urban storm. The storm intensity formula is the important basis for planning and designing the urban rainwater drainage system. According to a specific case and based on the storm intensity formula of Xinxiang City, the article puts forward the analysis methods of rainwater runoff in two separate drainage regions, including the rainfall duration options and statistical analysis, the spatial and temporal distributions of rainfall and the process of rainfall design, etc, which can be referred for the planning and design of urban rainwater utilization engineering and municipal drainage engineering.
