【摘要】：选取我国南方某城市一条基于低影响开发(LID)理念建设的道路,利用Info Works ICM城市综合径流模型模拟道路的降雨径流过程,评价生物滞留带的雨水滞蓄效果;另外,分析LID道路的场次径流总量削减率、峰值流量削减率、年径流总量控制率等指标及相关影响因素。结果表明,道路生物滞留带对中小降雨具有较好的控制效果,随着降雨量的增大,尽管统计所得的年径流总量控制率增大,但对降雨的径流总量控制能力减弱。
[Abstract]:A road based on the concept of low impact development of (LID) was selected in a city of southern China. The rainfall runoff process of the road was simulated by using the comprehensive urban runoff model of Info Works ICM to evaluate the effect of Rain Water stagnant storage in the biological detention zone. In addition, the reduction rate of total runoff at site, the reduction rate of peak flow, and the total runoff control rate of LID road are analyzed as well as the related influencing factors. The results show that the road biological retention zone has a good control effect on the moderate and small rainfall. With the increase of rainfall, the total runoff control capacity of the annual runoff is decreased with the increase of the annual runoff total control rate obtained by statistics.
