【摘要】:選取我國南方某城市一條基于低影響開發(fā)(LID)理念建設的道路,利用Info Works ICM城市綜合徑流模型模擬道路的降雨徑流過程,評價生物滯留帶的雨水滯蓄效果;另外,分析LID道路的場次徑流總量削減率、峰值流量削減率、年徑流總量控制率等指標及相關影響因素。結果表明,道路生物滯留帶對中小降雨具有較好的控制效果,隨著降雨量的增大,盡管統(tǒng)計所得的年徑流總量控制率增大,但對降雨的徑流總量控制能力減弱。
[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.
