Design of the Busan-Geoje Fixed Links Immersed tunnel
초록
Immersed tunnel had been a rather new term in Korea before Busan-Geoje fixed link project was started and became known through the media. Although Korean is unfamiliar with the immersed tunnel, this construction method has a long history in the world. Busan-Geoje Fixed Link immersed tunnel consist of 18 elements and each element is approximately 180m long. These tunnel elements are prefabricated of reinforced concrete in a temporary dry dock and are towed to the site and lowered into final position in a dredged trench and are placed on a screeded gravel bed directly without temporary support.
