摘　　要：利用ABAQUS非线性有限元程序,对船舶撞击航标桩的土体结构进行有限元动力分析,分别对无防撞设施和防撞设施分别为钢飘护舷和钢管防护架的航标桩受到撞击后的动力响应进行分析.通过应力、位移及加速度响应时程曲线对3种情况进行对比分析与优化选择.结果表明,采用钢飘护舷具有更好的防护作用.同时也提出了设计及使用的问题和建议,为今后推广和使用具有一定的指导意义.Employing ABAQUS nonlinear FEM program,analyzed dynamic response of the soil structure among three kinds of navigation mark pile which are bared navigation mark pile,navigation mark pile with floating steel fenders and navigation mark pile with steel protective.Proved that the navigation mark pile with floating steel fenders has be the best protective effect among the three kinds of devices by comparing response curves of stress,displacement and acceleration.Some suggestions are given on design of the navigation mark pile and how to use the method of finite element simulation which are of great value for promotion and use in the future.
