城市排水系统非恒定流模拟模型研究

Study on Unsteady Flow Simulation Model of Urban Drainage System

开发研制了城市排水系统非恒定流模拟模型．在暴雨条件下，可用此模型模拟排水管网的溢流、计算积水区的面积和水深．根据对已经建成的排水管网现状进行模拟计算的结果，提出了改造雨水管网系统和合流制管网系统的最佳设计方案．模型在实际应用中已经取得了很好的效果．

The model of urban drainage system unsteady flow simulation involves six blocks, namely the main program the database of storm drainage, the abstractions and losses block, the calculating inflow of sewer block, the transport block and the waterlogged areas calculating block. The model can be used for simulating sewer surcharge, calculating waterlogged areas and water depth under storm conditions. The best design of rebuilding storm sewer system can be provided based on simulating existing drainage pipeline. The model was used for rebuilding Shenyang drainage works last year, and the good result has been obtained
