摘　　要：为了全面客观评估城市排水管网的排水能力、预防城市内涝灾害的发生,基于EPA SWMM与ArcEngine技术,结合等流时线法与水量平衡原理,开发了城市内涝风险分析模型系统(USRAMS)。阐述了USRAMS的原理与功能,说明了利用USRAMS进行管网排水能力评估与内涝风险分析的方法,并验证了USRAMS的适用性;对沧州市进行了现状管网排水能力评估和城市内涝风险分析,以主题图的形式准确直观地表达了瓶颈管段位置以及城市内涝风险的分布情况。实例证明,USRAMS地表产汇流模块只需径流系数与汇水时间2个参数,较好地适应了中国当前情况,二维地表淹水模拟采用水量平衡原理,计算稳定、快速,其模型结果可为城市内涝防治与雨水管网系统的规划改造提供一定参考。In order to evaluate the pipeline drainage capacity and urban flood risk objectively,urban storm water risk analysis modeling system(USRAMS)is developed based on EPA SWMM and ArcEngine combined with the principle of equal flow time-line method and water balance.The principle and function of USRAMS and the method of assessing pipeline drainage capacity and urban flood risk with USRAMS are described,and the suitability of USRAMS is verified.Taking Cangzhou as an ex-ample,USRAMS is used to assess the pipeline drainage capacity and urban flood risk,and the position of bottleneck pipe and the waterlogging risk distribution are expressed in thematic map accurately and directly.The facts show that USRAMS only needs two parameters,namely the runoff coefficient and the catchment time,and adapts to the current situation in china better;two-dimensional earth surface waterlogging simulation adopts hydrologic budget theory,so its calculation is stable and fast.The results of USRAMS may provide reference for urban waterlogging prevention and control and the planning and reforming of stormwater pipe network system.
