Bohai Strait crossing passage is a strategic project,which has a significant role in boosting the development of Bohai surrounding economic zone and East China. In the paper,the construction mode,longitu-dinal profile,construction methods and planning of Bohai Strait crossing passage is further studied on basis of the common concept of tunnel crossing Laotieshan waterway. It is proposed that the form of full tunnel with two underground stations built in backfilled ground in the sea should be adopted for Bohai Strait crossing passage and that the tunnel should be constructed by open tunnel boring machine(TBM)method,with drill and blast as the assisting method.%渤海海峡通道对于推动环渤海经济区，乃至我国东部的高层次发展具有重大作用，是一项战略性工程。本文基于老铁山水道段采用隧道方式修建的共识，进一步论证了整个通道的修建方式、工程纵断面、施工工法的选择与工程的整体筹划，提出了渤海海峡通道以全隧道方式、考虑填海造地的两地下站布局，采用敞开式tunnel boring machine（TBM）为主、钻爆法为辅的配套修建技术与工法。
