中文摘要: 针对重庆万州长江公路大桥两端部分拱圈及立柱在三峡水库蓄水淹没时可能因船舶失控或走偏航道而碰撞垮塌的情况,提出了弧形水上升降式桥梁防撞装置,旨在防止此类恶劣事故的发生,并通过Abaqus有限元软件模拟了最不利工况下船舶撞击该防撞装置的过程。数值模拟结果表明,该装置具备较好的防撞能力,具有非常良好的发展前景。
Abstract:Part of the arch ring of Chongqing Wanzhou Yangtze River Road Bridge will be submerged when the Three Gorges Reservoir storages water to 175 m, and easily collided with the ship out of control or going off the channel. For preventing extremely badly safety accident, the round bridge anti-collision setting which lifts up and down with the water level was proposed firstly. Abaqus finite element was used to modeling the process of ship descends collision with the anti-collision setting. The anti-collision setting showed good crash capabilities.
