开辟长江口深水航道 ,在长江口内建立国际集装箱枢纽港是建成上海国际航运中心 ,以实现以上海浦东开发开放为龙头 ,尽快把上海建成国际经济、金融、贸易中心 ,带动长江三角洲和整个长江流域地区经济新飞跃的关键举措。在长江口南支南港的北槽采用整治与疏浚相结合的治理方案 ,修建双导堤和丁坝 ,以束水归槽 ,并浚深航槽 ,可以使长江口栏门沙滩顶水深从 6m分期加深到 8 5m、 10m和 12 5m ,最终使第三、四代集装箱船可以全天候通行 ,第五、六代超级集装箱船和 10万t级散货轮乘潮进出。
In order to establish Shanghai as an international economic,financial and trade centre it is essential to make Shanghai an international navigation centre.With the rapid development of container transport on a global scale,such an international navigation centre should possess hub port with container terminal capable of accommodating large or even super sized container vessels entering the port.Port Shanghai,located inside the mouth of the Yangtze River,is the only suitable site to build such container terminal,for it has the superiority of being in the immediate proximity of metropolis Shanghai,with superior facilities for conducting international trade and convenient access to the vast hinterland,including the delta area and the entire Yangtze River basin.At present,the only hindrance is the huge shoal forming at the mouth of the estuary,the natural water depth of the channels over the shoal is only 6m,vessels of over 10000 tonnage have to save the tide in entering the estuary.An improvement scheme has been worked out to increase the depth of entrance channel successively to 8 5m,10 0m and eventually to 12 5m,so that container ships of the 3rd and 4th generations could enter the port all day round,and those of 5th and 6th generations,as well as cargo vessels of 100 000 tonnage,by saving the tide.The improvement scheme consists of regulation works(training jetties and spur dikes)as shown in the figure,in combination with dredging operations.
