介绍了绍兴曹娥江袍江大桥的工程特点,利用经验公式与有限元方法对船与桥墩碰撞过程进行了模拟仿真,说明设计桥墩防撞装置的必要性。提出设计摩擦桩式防撞装置以保护桥墩,并对该装置的结构、防撞效果、防撞方式进行了分析。
The engineering features of the Cao’ao Jiang Pao River Bridge in Shaoxing are introduced. The collision process between the ship and the piers is simulated by the empirical formula and the finite element method. The necessity of designing the anti-collision device of the bridge piers is also illustrated. The friction pile anti-collision device is designed to protect the piers, and the structure, anti-collision effect and anti-collision mode of the device are analyzed.
