上海新港区金山咀入海航道比选

Conparison and Selection of Seaward Channel at Jinshanzui Shanghai New Harbour Area

本文是上海港务局委托的金山咀新港区通航第三代集装箱船可行性研究成果的一部分。作者首先简略地介绍了杭州湾3条航道的现状,提出了北、中、南3条航线供最后比较选择,然后依据近年的潮位资料进行了分析、计算,预测乘潮过浅的能力,最后得出了航线比选的结论:以大戢山灯桩为起始点的杭州湾南航道为最佳航线,通航吃水以10.5m以下船舶为宜;吃水11.0m以上船舶进入杭州湾已相当困难,故在杭州湾要通航第三代集装箱船应对航道浅段疏浚增深。

This thesis is one part of the feasibility study concerning operation of the third generation of container ships at Jinshanzui new harbour area entrusted by Shanghai Harbour Authority. The authors give a brief introduction of the present condition of there channels in the Hangzhou Bay for comparison and final choice. Then they make analysis, calculations and forecast on the capability of the channel for ships to pass through at high tdie according to the tidal information in recent years and reach the following conclusion: The seaward channel of the Hangzhou Bay started from the first light pole of Dajishan is the best choice where ships with a draft of less than 10.5m is no doult to operate. But it is quite difficult for ships with a draft more than 11m to enter the Hangzhou Bay. Therefore, the channel should be deepened for the operation of the third generation of container ships operate in the channel.
