摘要
基于Mike Urban软件建立城市内涝模型,本文对广州市花都区不同降雨情景下的内涝分布情况、易涝点积水时间以及最大积水深度进行模拟。研究表明,模拟结果与实际调研数据契合度高,该模型适用于城市内涝风险评估管理。其间考察研究区已建成的雨水管网存在的问题,通过Mike Urban对易涝点在30年重现期下的管网充满度进行模拟,通过排水管网改造与扩建、加设雨水泵站等措施提升管道排水能力。
An urban waterlogging model is established based on Mike Urban software,and the waterlogging distribution,waterlogging time and maximum waterlogging depth of waterlogging-prone points under different rainfall scenarios are simulated in Huadu District,Guangzhou City in this paper.The research shows that the simulation results are in good agreement with the actual survey data,and the model is suitable for urban waterlogging risk assessment and management.During this period,the existing problems of the rainwater pipe network that have been built in the study area are investigated,the fullness of the pipeline network of the flood-prone points under the 30-year return period is simulated by Mike Urban,the drainage capacity of pipelines is improved through measures such as the reconstruction and expansion of the drainage network and the addition of rainwater pumping stations.
