摘要
以广州市新河浦社区为研究区域,构建了基于Infoworks CS的城市雨洪模型,对研究区年均可收集雨量和需水量进行分析计算,并设计了雨水利用方案。采用Infoworks CS模型模拟了设置蓄水池、下凹式绿地和透水砖3种雨水利用措施在不同重现期时排水管道出口断面洪峰流量和淹没情况。结果表明,蓄水池、下凹式绿地和透水砖皆可有效地削减洪峰、推迟峰现时刻、减少径流量及被淹没节点数,三者组合可更好地发挥控制流量的作用,增加雨洪资源利用量,且重现期越小,雨水利用措施效果越好。
Taking Xinhepu community in Guangzhou City as study object, the urban stormwater model is developed based on Infoworks CS. The water balance is analyzed and the scheme of rainwater utilization is designed. Then, three kinds of measures, for example, storage pond, sunken lawn, and permeable brick based on Infoworks CS model are taken into consideration to test the change of the discharge and time of peak flow in the outlet of drainage channel during differ- ent rainfall return periods. The results show that storage pond, sunken lawn, and permeable brick can all effectively miti- gate peak flow, postpone the time of peak flow and reduce the runoff volume and the number of the wells inundated by rainwater; combination of three measures can better control the discharge and enhance the rainwater utilization; the shorter the return periods are, the better rainwater utilization measures work.
