长江口12.5米深水航道投入运行两年来，通航水深保证率保持在95%以上，吃水12米以上船舶通过量增幅明显，2012年通过530艘次，较2010年增长18.92倍。

长江口12.5米深水航道投入运lineOver the past two years,Navigable depth assurance rate above 95%,12 meters above ship draft by quantity increase obviously,In 2012 through the 530 ships,A increase from 2010.

　　2011年5月18日，长江口深水航道工程全面竣工。两年来，长江口航道管理局始终把水深线视为“生命线”，坚持不懈抓维护疏浚管理，确保水深通航保证率。航道水深的持续稳定，带来了大型船舶通航量的持续攀高。海事部门数据显示，2012年通过长江口深水航道的船舶总量为47536艘次，日均149艘次，较2010年长江口12.5米深水航道试通航当年的43041艘次增长了10.44%。交通运输部水运科学研究院统计表明，通航船舶大型化趋势强劲，2012年通过长江口深水航道的船舶平均载重吨已达35477吨。2012年通过长江口的货运量为10.5亿吨，较2010年增长15.4%。长江口深水航道对上海国际航运中心建设发展起到了有力的支撑作用。上海港2012年完成货物吞吐量7.36亿吨、集装箱吞吐量3253.9万标箱，其中有约60%是在长江口内港区完成的。

2011年5月18日,Yangtze estuary deepwater channel project fully completed.Over the past two years,As Yangtze estuary waterway administration has the depth of the water line"The lifeline",Persistence management maintenance dredging,To ensure that the water depth of navigation reliability.Channel depth steadily,Brought a large amount of ship navigation persistently high.海事部门数据According to,In 2012 through the Yangtze estuary deepwater channel to ship total 47536 ships,Daily average of 149 ships,From 2010, the Yangtze estuary deepwater channel 12.5 meters test flights in 43041 ships has increased by 10.44%.The traffic运输部水运科学研究院统计表明,Navigation of ship strong large-scale trend,In 2012 through the Yangtze estuary deepwater channel of vessel deadweight tonnage has reached an average of 35477 tons.Through Yangtze river estuary in 2012 volumes of 1.05 billion tons,Up 15.4% from 2010.长江口深水航道对上海国际航运中心建设发展since到了有力的支撑作用.Shanghai complete cargo throughput of 736 million tons in 2012/Container throughput of 32.539 million teus,About 60% of them done within the Yangtze river estuary port.
