摘　　要：雨天杨公堤污水系统内松岳、卧龙、新茶博泵站污水增量明显、雨污混流情况严重,新茶博最高雨水混入比达到74.7%。InfoWorks ICM模型拟合显示,降雨量大于30 mm时,杨公堤污水系统上游管线出现容纳量不足现象。分析降雨对杨公堤污水系统影响,对调度运行和雨污分流工作具有指导意义。In rainy days,the increment of sewage in Songyue,Wolong,and Xinchabo Pumping Stations in Yanggongdi Sewage System is obvious and the mixing of rain and sewage is serious,while the maximum ratio of rain mixing in Xinchabo Pumping Station is 74.7%.The InfoWorks ICM model fitting shows that the upstream pipeline of Yanggongdi Sewage System has insufficient capacity as the rainfall is greater than 30 mm.To analyze the influence of rainfall on the sewage system of Yanggongdi Sewage System is of guiding significance for subsequent dispatching operation and the work of rain and sewage diversion.
