摘　　要：跨航道桥梁存在船撞风险,因此有必要研究桥梁船撞安全性.采用非线性有限元模拟了船-桥碰撞过程,讨论了船舶速度和吨位对撞击力的影响.根据桥梁特点设计了复合材料夹层防撞结构,并采用数值方法模拟了船舶、防撞结构和桥梁之间的相互作用,分析了碰撞过程中防撞结构的形变和失效机理.计算结果显示,防撞设施内部蜂窝型夹层结构提供了较好的受力传播路径,具有较好的耐撞性,浮式套箱使桥墩所受船撞力大幅减小,能够很好保护桥墩和船舶.The nonlinear finite element method is used to simulate the ship-bridge collision process,and the influence of ship speed and tonnage on the impact force was discussed.According to the characteristics of bridge,the composite sandwich anti-collision structure was designed,and the interaction between ship,anti-collision structure and bridge was simulated by numerical method,and the deformation and failure mechanism of anti-collision structure during collision were analyzed.The calculation results show that the honeycomb sandwich structure inside the anti-collision facilities provides a good stress propagation path and has good crashworthiness.The floating boxed set can greatly reduce the collision force on the pier and protect the pier and the ship.
