| 摘 要： | 鱼嘴长江大桥为主跨616 m的单跨悬索桥.北岸桥塔位于水中,有受到船舶撞击的可能性.北塔横桥向撞击力为19 000 kN,顺桥向撞击力为9 5500 kN,塔柱设计主要由横桥向船撞工况控制.通过在桥塔横桥向两塔柱间设置1道底横梁,并将下段塔柱设计为实心截面,依靠桥塔自身来抵御船舶横桥向撞击.分析结果表明,这种桥塔设计满足设计规范要求,解决了桥塔横桥向防撞问题.

| Abstract: | Yuzui Changjiang River Bridge is a single-span suspension bridge with main span 616 m.The north tower of the Bridge is located in the river and the tower has the possible risk of being collided by ships.The anti-collision capacity of the tower in the transverse direction of the Bridge is designed to be 19 000 kN while that of the tower in the longitudinal direction is 9 500 kN.The design of the tower pile foundation is mainly governed by the collision load case in the transverse direction and the tower itse... |
