abstract="The Geogeum Bridge is a part of a fixed connection from Geogeum Island to Sorok Island located in the southernmost part of Korean peninsula. This bridge carries a two-lane national highway and has a total length of 2028 m, which is composed of a 912 m approach bridge and a 1116 m main bridge. The bridge girder is a 6 m high composited truss girder with a carriageway on the upper concrete deck and a walk and bicycle path on the lower steel deck. The pylons are diamond-shaped concrete structures with a height of 1167,5 m. The cables have been arranged in bundles, which are believed to create a visual appearance similar to rays of sunlight penetrating through the clouds. The stay cables for each pylon are arranged in three bundles in one central plane, anchored at the top of the bridge girder and at steel anchorage boxes in the center plane of the pylons. The prefabricated 72 m large girder segments including concrete deck were lifted up and placed on temporary support on jack-up barges by using a floating crane. Seven stays in each bundle were stressed all together. Based on this construction method, it took nine months for construction. Compared with a traditional erection method using derrick crane, it is believed that the chosen method with large segment is superior in terms of construction speed and minimizing the amount of work at site.<p /> <p>Language: en</p>",
