摘要
对某城市污水管网建立SWMM模型进行水力模拟,并对其运行后得到的流速、充满度等数据进行综合分析。研究表明,流速慢且充满度大的管段更容易产生淤积且较为严重。据此找出研究区域内容易发生淤积及淤积严重的管段,并确定管网的淤积风险级别。通过对找出的易发生淤积及淤积严重管段进行校核,验证了分析结果的正确性。通过建立模型并分析流量及充满度,可有效预测排水管网的易发生淤积及淤积严重管段。
The SWMM model of a municipal sewerage network was established for hydraulic sim-ulation, and the data of velocity and depth ratio obtained after its operation were analyzed synthet-ically. The results showed that the section with slow velocity and high depth ratio is more prone to silt and is more serious. Based on this, the pipe sections which are prone to siltation and serious siltation in the study area were found out, and the risk level of siltation in the pipeline network was determined. The correctness of the analysis results was verified by checking the easy siltation and serious silt section. By establishing the model and analyzing the discharge and the filling degree, it can effectively predict the easy siltation and the serious silting section of the drainage pipe network.
