为了研究万州长江公路大桥防撞装置的通航适应性,分别采用有限元软件ABAQUS、物理模型试验等方法对该装置的结构稳定性及通航净空进行了分析.模型计算和试验结果表明,船舶撞击防撞带后,防撞带保持了较好的完整性,船舶也未出现擦刮大桥拱圈和自身翻覆现象,满足桥、船和防撞设施“三不坏冶原则,防撞装置对大桥能进行有效地防撞保护.

In order to study its navigation adaptability, the structural stability and navigation clearance of an anti-collision device of the Wanzhou Yangtze River Highway Bridge were analyzed by means of the finite element software ABAQUS and a physical model. The calculated and experimental results show that the anti-collision belt maintains the structural integrity after being hit by a ship, and the ship can pass through the bridge safely without rubbing the bridge arch. Thus, the anti-collision device of the Wanzhou Yangtze River Highway Bridge can meet the security requirements of the ship and the bridge, as well as its own, and it can provide effective protection for the reservoir bridges.
