摘　　要：在监测管道流量、对系统所属泵站SCADA(数据采集、监控系统)数据和受纳水体苏州河水位在线监测值详细统计分析的基础上,建立了基于当量连接管的水力模型分析方法.基于当量管道和水量平衡原理,通过系统水力模型分析,准确地确定了上海市某雨水系统的雨污混接水量,同时确定了该水泵强制排水系统存在的严重的地表水流入情况及流入水量.Sewer flow monitoring was carried out; Supervisory control and data acquisition （SCADA） data of the pump station and the water level log of Suzhou Creek were collected and analyzed, and then on the basis of skeletonizing complex illicit connections into equivalent connecting pipes, and calculating the equivalent pipes specific parameters by water quantity balance, the sewer system hydraulic model was built up. Modelling water level graphs match the measured quite well. The flow of illicit connections to the storm system and inflow from Suzhou Creek are indicated definitely. The methodology is applicable to various sewer systems with complex hydraulic connections, and the work is significant to the remediation plans for the illness drainage systems.
