【摘要】：选取浙江省桐庐县老城区作为研究区域,以构建SWMM模型为研究手段,选择雨水收集桶、植被浅沟、透水铺装和绿色屋顶4种LID措施,并根据当地实际情况对组合布设方式进行了优化。分别对传统开发情形和LID开发情形下老城区遭遇1年一遇、2年一遇、5年一遇重现期暴雨时的积水深度和范围进行了模拟分析。结果表明,LID措施能够削减洪峰流量,推迟峰现时刻,显著减少内涝积水深度和范围,降低了老城区所面临的内涝风险。
[Abstract]:This paper selects the old urban area of Tonglu County, Zhejiang Province as the research area, takes the SWMM model as the research means, chooses Rain Water to collect the bucket, the vegetation shallow ditch, the permeable pavement and the green roof four kinds of LID measures. And according to the actual situation of the local combination of the layout of the optimization. The depth and range of water accumulation in the old urban area under the traditional development situation and the LID development situation are simulated and analyzed respectively when the rainstorm occurs once in 1 year, once in 2 years and once in 5 years. The results show that lid can reduce the discharge of Hong Feng, delay the peak time, reduce the depth and scope of waterlogging, and reduce the risk of waterlogging in the old city.
