| 摘 要： | 研究提出了基于单场次降雨分析以及基于长系列降雨统计的生物滞留设施规模设计方法。针对国内市政排水设计一般采用设计重现期的概念,基于单场次降雨分析的规模设计方法用暴雨强度公式和雨型分配方法计算设计降雨过程,由设计降雨推算设施入流过程,用水量平衡法推算出流过程,用洪量削减率、洪峰削减率、洪峰延迟时间评估设计效果。基于长系列降雨统计的规模设计方法对长期日降雨量进行统计分析,得出不同降雨发生频率对应的设施入流量及处理量,用年径流总量削减率评估设计效果。

| Abstract: | This study offered a scale design method for the bioretention facilities based on single storm analysis and long seriesrainfall statistics. As for that the design return period of rainfall is usually used in municipal drainage design in China, in thescale design method for the bioretention facilities based on single storm analysis, the design rainfall process was calculated by us -ing the storm intensity formula and rainfall distribution, the facility inflow process was calculated with the design rainfall process,and the outflow process was derived by using the water balance method. In this case, the hydrological effect was evaluated by therunoff reduction rate, peak flow reduction rate and peak flow delay time. Otherwise, the long-term daily rainfall was analyzed byusing the scale design method based on long series rainfall statistics, by which the inflow and treated outflow of the facilities underdifferent rainfall frequencies were calculated and the annual runoff reduction rate was used to evaluate the hydrological effect. |
