摘 要: 数值仿真是进行船桥碰撞研究的一种重要方法,先对船桥碰撞数值模拟中涉及到的材料本构模型、网格划分、流固耦合作用及其简化、摩擦作用和桩土相互作用等五个方面的问题进行了总结归纳,并给出了某桥梁船撞问题的分析实例,最后对船桥碰撞数值模拟技术的发展做出展望。 Numerical simulation is an important tool for the research on ship-bridge collision. The modeling techniques in the five aspects (material constitutive model, mesh, fluid-solid coupling and its simplification, friction, pile-soil interaction) of a ship-bridge collision incident simulation are firstly summarized, and a numerical analysis process for a certain ship-bridge collision is given. Last, a preliminary prospect for future development of the ship-bridge collision simulation is presented.
