基于SWMM模型的沧州市区暴雨积水深度模拟

Simulation of Rainstorm Waterlogging Depth in Cangzhou City Based on SWMM Model

目前我国许多城市承受着暴雨内涝灾害的困扰,严重影响市民生活质量,威胁着市民生命、财产安全。针对城市防洪排涝需求,为提高城市排水管理效率,最大限度地减少暴雨积水带来的危害,基于沧州市区排水管网现状,利用SWMM模型构建了沧州市暴雨积水计算模型,利用实测降雨、积水资料对模型进行了检验。结果表明,模型精度较高,可为城市排水管网改建、规划设计提供依据。

At present,many cities in China are under the rainstorm waterlogging disaster,which seriously affects pepple＇s life quality,threatens their life and property safety.According to the requirements of city flood control and drainage,to improve the efficiency of urban drainage management,minimize the harm done by the heavy rain water,Cangzhou rainstorm waterlogging calculation model has been established with SWMM model based on the cause of the urban drainage pipe network status quo.The data of rainfall and water is adopted to test the model.The results show that the model has high precision,and can provide a basis for the urban drainage pipeline network reconstruction,planning and design.
