摘要
分别以上海市苏州河沿岸某排水系统和合流污水治理一期工程截流总管为研究对象，利用排水系统水力模型对雨天流入水量进行了模拟研究．结果表明，台风暴雨与高潮位碰头引起的苏州河水位升高，使得大量河水通过原重力直排管道未封堵完善的出流口倒灌进入管网系统，造成相应情况下泵站排放水量超过径流水量的10％～20％仍无法排除雨涝积水．研究结果为制定苏州河沿岸排水系统改造方案，控制上海市区雨涝灾害提供了可靠依据．
The wet-weather inflow of a small drainage system along Suzhou Creek and the main interception system of Shanghai＇s combined Sewerage treatment project Phase I （SSPI）was analyzed with drainage hydraulic model. Result shows that the level of Suzhou Creek rises due to typhoon storm and high tide level, and the river water flows backward to drainage networks through abandoned gravity discharge pipes which are not completely blocked after the systems are changed from gravity drainage to pump drainage. As a result, even the pumped water volume is 10%-20% larger than the real runoff, the flooding of catchments still cannot be avoided. The analysis result provides valuable suggestion on the improvement of drainage systems and the flooding control for Shanghai center area.
