摘　　要：针对暴雨导致的城市内涝淹水问题,利用地理信息系统(GIS)技术,构建了淹没分析模块,结合SWMM模型,实现了对城市暴雨内涝淹没范围和淹水深度的模拟分析。并以华南沿海某城市区域为例,进行了设计和典型暴雨条件下的模型计算。结果表明,基于GIS的淹没分析模块设计合理,计算结果较理想、可靠,能直观表现受涝区淹没范围和淹水深度,在城市排水管网规划、雨洪管理和灾后损失评估等方面具有一定的应用价值。Aiming at the rainstorm waterlogging and submergence in urban areas, a submergence analysis module based SWMM model was developed to simulate the distribution of submergence area and the depth of rainstorm waterlog ging by using GIS technology. Taking a coastal urban area of South China for an example, the results for designed and typical rainstorms show that the design of submergence module based on GIS is reasonable, and the simulated calculations are reliable. The module can generate graphic distributions of submergence effevtively, which is helpful to drainage network planning, storm-flood management and waterlogging damage assessment.
