Abstract: |
Yi Sun-sin Bridge or 1545 Bridge having the total length of 2260m suspension bridge with a main span of 1545m is under construction to promote the future investments for Gwangyang Harbour and Hallyeohaesang National Park area and to establish tourism development infra for the International EXPO 2012 held in Yeosu in the southern seashore of the Korean peninsula. World’s 4th ranking main span length of 1545m has been determined to commemorate famous Korean Admiral Yi Sun- sin’s birth year and to accommodate the future passage of the 18000 TEU (twenty-foot equivalent unit)-class container ships for Gwangyang Harbour. Saving the construction cost and achieving the structural stability were main concerns in the planning and detail design of Yi Sun-sin Bridge with 1545m main span. As a result, high-strength steel of 1860MPa for the main cables, newly developed streamlined twin box stiffening girders, 50mm thickness of epoxy asphalt pavement, etc. were adopted to satisfy the design purposes. |
