摘要
以重庆市渝北区花朝工业园为研究对象,分别设计单一生物滞留池、渗透性路面、绿色屋顶控制方案以及生物滞留池-渗透性路面-绿色屋顶组合式方案,构建SWMM模型模拟不同方案对研究区域的径流、洪峰削减影响效果。模拟结果表明,LID措施的径流削减效果在重现期为2年、10年时更显著;单一方案中渗透性路面的径流控制效果与洪峰削减效果更显著;组合式方案的径流控制效果优于单一方案的和值,表明彼此间相互产生正影响。组合式方案的洪峰削减效果低于单一方案的和值,表明彼此间相互产生负影响。
Taking Huachao Industrial Park in Yubei District of Chongqing as the research object,single scheme and combined scheme of biological detention pool,permeable pavement and green roof were designed respectively,and SWMM was constructed to simulate the effects of different schemes on the study area.The simulation results show that the runoff reduction effect of low impact development(LID)measures is more significant when the recurrence period is 2 years or 10 years.The runoff control effect and flood peak reduction effect of the single scheme of permeable pavement is more significant.The runoff control effect of the combined scheme is better than the sum value of single schemes,which shows that they have a positive impact on each other.The peak reduction effect of the combined arrangement scheme is lower than the sum value of single schemes,which indicates that they have negative effects on each other.
