- 摘要:
- 针对老城区内涝问题，以徐州市泰奎大沟排水分区为例，利用MIKE FLOOD模型，采用系统性治水思维，耦合城市雨水管网、水系及地形地物，分析评估现状以及规划方案下的积水深度与积水时间，剖析老城区现状内涝成因，并提出新建截洪沟、完善雨水管网系统、增设河口泵站、增加雨水调蓄池等多种措施为一体的综合治理方案。模拟结果显示，在规划方案中，积水深度<15 cm、积水时间<1 h，表明所提出的内涝治理系统化措施合理，可为老城区内涝防治提供基本思路。
- Abstract:
- MIKE FLOOD model was applied to analyze and evaluate the waterlogging depth and time under the current situation and planning scheme based on systematic stromwater control strategy, urban storm sewer system, urban river system, urban topography and surface features, so as to solve the waterlogging problem in old urban districts of Taikui Gully drainage area in Xuzhou City. The paper analyzed the causes of waterlogging in the old urban district, and proposed a comprehensive control scheme, including constructing new flood interception channel, improving rainwater pipe network, adding river gates and pumps, increasing rainwater storage tanks and so on. The simulation results showed that the waterlogging depth and time under the planning scheme were less than 15 cm and 1 h, indicating that the proposed systematic measures of waterlogging control were reasonable and could provide a basic idea for waterlogging prevention and control in old urban districts.
