| 摘 要： | 以北京市奥林匹克公园为研究区,采用美国环保局开发的SWMM(Storm Water Management Model),对研究区内下凹式绿地和蓄水池两种措施条件下排水管道主要断面洪峰流量的变化进行了计算分析.计算结果表明,下凹式绿地和蓄水池可以有效地削减洪峰,推迟峰现时刻,减小径流系数,从而增加雨洪资源利用量.

| Abstract: | Nowadays more and more cities are suffering from scarcity of water resources. In order to use stormwater sufficiently, some measures of rainwater utilization, such as storage ponds, sunken lawn and pervious road pavement, are taken in many cities. In this paper the impacts of sunken-lawn and storages pond on urban flood are analyzed in Beijing Olympic park by using SWMM model. The flood peak flow at main sections of rainwater drainage pipes is calculated under the conditions with sunken-lawn or storage ponds. The results show that flood peak and the runoff coefficient can be reduced effectively, the peak time postponed and meanwhile the amount of rainwater utilized as resources increased. |
