摘要
随着城市化进程的加快,城市暴雨积水对人们生活的影响越来越大。选用暴雨管理模型SWMM,利用GIS和RS技术计算了暴雨积水的相关数据,分析了由暴雨引起的地面和管网积水的特性与持续过程;研究了GIS与SWMM耦合集成将积水过程三维动态仿真的方法。研究结果表明,将GIS技术和RS技术应用于SWMM的计算分析过程中可大大提高计算的效率和计算结果的精度,而三维动态仿真提供了更为直观和有效的预测手段,可提高应急指挥能力。
With the speedup of urbanization,the effect of urban storm waterlogging on people＇s lives is increasing. In this paper,the storm sewer model-Storm Water Management Model（SWMM）,GIS and RS Technology was used to calculate relative data of the urban rainstorm,the characteristic and the process of rainstorm water on the ground and in the pipeline had been analyzed,and the methods of integrating GIS and SWMM had been studied to realize 3D dynamic simulation for the process of rainstorm waterlogging.The results showed that the application of GIS and RS technology in the process of calculating can extremely improve the efficiency of cal- culation and the precision of its results.The 3D dynamic simulation had offered a kind of prediction method with more direct-viewing and effective characteristics,which can be applied to establish flood-mitigation measures.
