摘　　要：通过物理模型试验，研究了海水入侵具有上升管的扩散器形成循环阻塞的机理和影响循环阻塞冲洗的因素；建立了循环阻塞的临界冲洗流量及相应的临界密度佛劳德数的理论计算模式，并在试验中得到了很好的验证．In this paper, a physical model is used to study the mechanism of circulation blocking by which seawater intrudes the sewage outfall diffuser with multi-riser, and the various factors affecting the critical densimetric Froude number to purge the circulation blocking are studied. The mathematical formulas of the critical port densimetric Froude number and the critical sewage discharge are derived, which have well been testified by the experiment results.
