- 摘要:
- 根据北方平原区域的地形和排水管网布置特点,提出了通过构建环状排水管网来提高区域排水防涝能力的方案,并以北京市某区域为例,采用MIKE FLOOD模型,系统分析了树状排水管网改为环状排水管网后对区域排水防涝安全的提升效果。模拟结果显示,相比树状管网,环状管网的平均充满度削减率为5.43%~14.29%、充满度标准差削减率为25.00%~35.71%、超载管段削减率为33.33%~66.67%、管网进入二维地面的积水总量削减率为26.16%~38.13%、积水点削减率最高可达50%,表明环状管网能有效提升排水管网的空间利用率,改善管网的运行状态,减少积水点,并显著降低地面积水风险。构建环状排水管网能够提升区域水安全保障能力,可为区域排水管网升级改造、排水系统优化设计,特别是地势相对平坦的已建成区的排水防涝能力提升提供参考。
- Abstract:
- According to the terrain and drainage network layout characteristics of northern plain regions, this paper proposed a scheme to improve regional drainage and waterlogging prevention capacity by constructing looped drainage network, and the improvement of regional drainage and waterlogging safety after branched drainage network being changed to looped drainage network was systematically analyzed by using MIKE FLOOD model. Compared with the branched network, the reduction rate of average depth ratio of looped network was 5.43%-14.29%, the reduction rate of the depth ratio standard deviation was 25.00%-35.71%, the reduction rate of the overload pipe section was 33.33%-66.67%, the reduction rate of the ponded water volume from the pipe network into the two-dimensional ground was 26.16%-38.13%, and the maximum reduction rate of ponding points reached 50%, indicating that the looped network effectively increased the space utilization rate of drainage network, improved the operation status of pipe network, decreased the ponding points, and significantly reduced the ponding risk. The construction of looped drainage network improved the regional water security capability, and provided a reference for the upgrading and reconstruction of regional drainage network and the optimization design of drainage system, especially for the improvement of drainage and waterlogging prevention capacity in built?up areas with relatively flat terrain.
