| Abstract: | The Tsugani Strait Bridge is proposed over the Tsugaru Strait, with the distance of 19km and the greatest depth of 270m,between Honsyu and Hokkaido in Japan. The Bridge is planned with 1 continuous suspension bridge with 2 spans of 4,000m in the center, to secure the international navigation route, and 2 suspnsion bridges with 2,000m central span on both sides. To realize these bridges, a suspension system with a combination of 3 main cables and sub-cables, 2 separated steel decks, cable stayed prestressed concrete decks, jacket piers with inclined legs and joint anchorages between 2 suspension bridges are proposed. Through these measures, such benefits as reduction of cable tension, wind stability, possibility of re-erection, minimizing displacements of tower tops and decks for seismic force, reducing preparatory works, cancellation of tractions at the anchorages etc. can be obtained. The Tsugaru Strait Bridge shall be the new goal of bridge engineering in Japan, after the Akasi Strait Bridge |
