摘　　要：MIKE FLOOD是一款功能强大的水动力模型,常被用作对精度要求不高的市级或流域尺度的雨洪模拟。针对居住小区的重要性和小尺度性特点,以深圳某居住小区为例,基于MIKE FLOOD构建1.5 m×1.5 m精度的管网和地表耦合模型。模拟结果显示,有33%的管网排水能力小于1 a,54.5%的管网排水能力大于5 a。模拟50年一遇暴雨条件下,区域内共有6处积水情况,其中最大积水深度高于1.2 m,且最大积水时长大于19 h。研究结果,为工程提供科学的决策依据。MIKE FLOOD, as a powerful hydrodynamic model, has been widely used as a rain or flood simulation at a municipal or basin scale with less stringent accuracy requirements. Aiming at the importance and small-scale characteristics of the building community, a residential area in Shenzhen is taken as an example to build a 1.5 m×1.5 m precision pipe network and surface coupling model based on Mike Flood. The simulation results show that 33% of the pipe network drainage capacity is less than 1 year, and 54.5% of the pipe network drainage capacity is greater than 5 years. Under the simulated 50-year rainstorm conditions, there are six water accumulation conditions in the region, the maximum depth of which is higher than 1.2 m, and the maximum water accumulation time is longer than 19 hours. The research results could provide scientific decision-making basis for engineering.
