基于水量平衡原理,通过管道水力模型计算与现场流量及水位监测,研究考察了不能直接应用夜间最小流量法的水泵强制排水系统地下水渗入量的水力模型辅助评估方法,据此评定了上海市某混接雨水系统旱流截污运行条件下的地下水渗入量,并对该方法的应用条件进行了分析讨论,为排水系统管理与地下水渗入量研究提供了借鉴。
Based on the principle of water balance and the calculation of pipeline hydraulic model and on-site flow and water level monitoring, a hydraulic model aided assessment method of groundwater infiltration of forced drainage system of water pump that can not directly apply night minimum flow method was studied. The groundwater infiltration under the condition of interception and drainage of rainwater system was analyzed. The application conditions of the method were analyzed and discussed, which provided references for the study of drainage system management and infiltration of groundwater.
