【摘要】：選取浙江省桐廬縣老城區(qū)作為研究區(qū)域,以構(gòu)建SWMM模型為研究手段,選擇雨水收集桶、植被淺溝、透水鋪裝和綠色屋頂4種LID措施,并根據(jù)當?shù)貙嶋H情況對組合布設(shè)方式進行了優(yōu)化。分別對傳統(tǒng)開發(fā)情形和LID開發(fā)情形下老城區(qū)遭遇1年一遇、2年一遇、5年一遇重現(xiàn)期暴雨時的積水深度和范圍進行了模擬分析。結(jié)果表明,LID措施能夠削減洪峰流量,推遲峰現(xiàn)時刻,顯著減少內(nèi)澇積水深度和范圍,降低了老城區(qū)所面臨的內(nèi)澇風險。
[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.
