摘要

Since 1988, Nippon Steel Corporation has developed a new submerged tunnel tube construction method consisting of prefabrication method which does not required a dry dock, composite structure, and reliable flexible joint. The Kobe Minatojima Submerged Tunnel, the first steel-concrete sandwich tunnel tube, was constructed in the dry dock. And this development has completed with the completion of The Naha Submerged Tunnel, which the double-skin steel tube shell body including a bellows joint was towed to Okinawa from Kitakyusyu, and was placed high fluidity concrete while afloat early spring in 2001.
