摘要
京杭运河二通道钱塘江出口拟建在七格弯道,该河段受山潮水双向水流作用,水动力强,水体含沙量高,河床冲淤幅度大,沿岸护岸丁坝群及其它涉水建筑物较多,致滩槽冲淤变化复杂。在河床演变分析的基础上,采用动床模型试验研究各治理方案的效果,进而提出合理的治理方案。
The Second Outlet of Beijing-Hangzhou Canal locates at Qibao Concave Bank of Qiantang estuary. Qibao Curved reach is unsteady and the riverbed is variational because of reversing current. The paper recommends the treatment proposal after studying the effects of treatments with the method of moveable bed model combined with the analysis of the bed evolution data.
