- 摘要:
- 采用情景模拟法，利用ArcGIS和Mike工具构建不同降雨重现期下雨水管渠、水系和地表径流模块，通过Mike Flood工具将三者进行耦合分析，模拟设计降雨工况下的城市内涝积水情况。基于模拟结果分析排水管渠水力负荷，评估城市雨水管渠系统排水能力，同时利用ArcGIS对积水深度、积水时间及地区重要性进行叠加分析，采用层次分析法将研究区域划分为高风险内涝区、中风险内涝区和低风险内涝区，为城市排水管渠改造、内涝点治理、竖向规划、用地规划等提供科学依据，同时提高了城市防涝管理水平。
- Abstract:
- Rain water pipes, river systems and surface runoff modules in different rainfall return periods were constructed by using scenario simulation method and ArcGIS and Mike tools, and urban waterlogging under the design rainfall condition was simulated through coupling analysis of the three by Mike Flood tool. Based on the simulation results, hydraulic load of drainage pipes was analyzed, and drainage capacity of urban rain water pipe was evaluated. Meanwhile, overlay analysis of ponding depth, time and regional importance was carried out by ArcGIS, and the study area was divided into high risk waterlogging area, middle risk waterlogging area and low risk waterlogging area by analytic hierarchy process (AHP). The works desired to provide scientific basis for urban drainage pipes renovation, waterlogging control, vertical planning and land use planning, and improved the level of urban waterlogging prevention and management.
