摘要
以SWMM为平台,选取天津蓟县某典型区域,进行不同降雨强度条件的暴雨模拟,识别积水节点和满流管段的分布以及排水管网运行瓶颈。在此基础上,基于绿色屋顶、下凹式绿地和渗透路面3种低影响开发(LID)技术措施提出适用于该区域的雨水控制方法,并采用SWMM中的LID模块对雨水控制效果进行模拟。结果表明,LID技术对积水节点和满流管段削减效果显著,能有效降低城市内涝风险。
Based on SWMM, a typical urban region from Tianjin Jixian area was selected to sim- ulate the storm in the scenarios of different frequencies, as well as to identify the distribution of ponding nodes, the full flow pipes and the bottlenecks of drainage network performance. On this basis, the stormwater control method of this region was put forward by adopting three kinds of Low Impact Development （LID） measures including green roofs, recessed green space and perme- ant loads. Then, the LID module in the SWMM was adopted to simulate the stormwater control- ling effect. The result showed that the reduction effect of ponding nodes and full flow pipes was significant. Thereby the risk of urban water logging was able to be reduced.
