Abstract

This study examines the construction process of the Seikan Tunnel. Through this, I have made suggestions for the future discussion on the construction of the Underwater tunnel between Korea and Japan. The following framework of analysis was used for this purpose: 1) Natural basic conditions of the Tsugaru Strait, 2) Limitations of construction and technology, and 3) Active development of tunnel construction technology. In particular, it was predicted that the construction of the Seikan Tunnel was a difficult construction. The rapid sea currents, deep seas, and the complicated submarine geology of the Tsugaru Strait made the construction very difficulte. Above all, fragile geology and complex geotechnical structures could not be resolved by civil engineering and equipment at that time. Nevertheless, Japan has developed a new tunnel construction technology and completed the Seikan Tunnel. As a result, Japan has established a relatively safe railway infrastructure. In particular, Japan has developed underwater tunnel excavation technology in the process of constructing the Seikan tunnel. As a result, Japan has the world's most advanced tunnel technology. These facts are expected to provide policy implications for discussions on the construction of the Underwater tunnels between Korea and Japan to be developed in the future.
