Abstract
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,longitudinal 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.
