摘　　要：近年来我国港口码头泊位超负荷运行的情况渐多,随着码头泊位靠泊能力的升级,码头结构遭受破损荷载冲击的可能性在加大。结合某港口码头抓斗碰撞事故的实例,采用ANSY/LS-DYAN有限元分析软件对该事故进行数值仿真计算,分析码头横梁的破损原因和整个碰撞过程的能量转换,通过编程后处理研究码头横梁的受力状态及规律。For recent years, many terminals operate at an overload in China. The upgrade of berthing capacity leads to the probability of the wharf structure being impacted by damaged load. Finite element software ANSY/LS-DYAN is applied to simulate the accident that two grab bucket cranes collide each other on the wharf, and analyze the cause for damaged beams and the power transformation in the collision process. Then relevant programming work is completed so as to research and deal with the state and law of the stress on the beams.
