Girder of 3rd Kurushima Kaikyo Bridge -The World's First Three-Linked Suspension Bridge with a Stiffening Box Girder of Over 1 000 m Long- Akihiro Uemura, Kyotaro Kanda, Tomohide Sakamoto, Shinichiro Ito |
| Synopsis : Kurushima Kaikyo Bridge, which consists of three bridges crossing the Kurushima Strait located within Seto Inland Sea National Park, is the first three-linked suspension bridge in the world. Many advanced technologies were adopted in the construction of the bridges. Especially, the introduction of a newly-developed self-positioning barge and a quick-joint-system enabled to install shop-fabricated stiffening box girders merely in 30 min by means of a direct hoisting method. 3rd Kurushima Kaikyo Bridge, which is one of the three bridges, spans over the west channel of the straits where the international sea route passes through. The bridge has a single span of 1 030 m long with two-hinged stiffening girders. This paper describes the design, shop fabrication and erection work of the stiffening girder at the site of 3rd Kurushima Kaikyo Bridge. The results obtained through this construction are expected to contribute to the success in the strait crossing bridge projects in the future. |
