摘　　要：钱塘江河口潮强流急,河床大冲大淤,主流摆动频繁,航线不固定,难以采用常规方法分析确定进港航道通航水深保证率。以上虞液体化工码头工程为例,利用长系列水文地形实测资料,分析工程河段水文、河床演变特征及航道条件,据此计算进港航道通航水深保证率,提出码头通航所需条件及优化建议。The Qiantang River estuary is characterized by macro-tide and rapid current,and the riverbed is significantly eroded and silted.Therefore,the mainstream swings frequently and the route is unstable,which is not conducive to ship navigation and wharf operation.Taking Shangyu Liquid Chemical Wharf Project as an example,based on the analysis of long time series of field data,the evolution mechanism of river bed in this reach is deduced,and then the navigation depth guarantee rate of the inlet channel in the macro-tidal estuary is obtained.Finally,the conditions and optimization suggestions for the navigation of the wharf are proposed.
