摘要(Abstract)：

基于ANSYS/LS-DYNA有限元软件显示动力分析,采用非线性动态有限元法,对海底管道受坠物碰撞的动态过程进行数值模拟,对比分析坠物质量、坠物形状、轴向预加荷载因素对海底管道在撞击作用下凹陷及损伤区域的影响。结果表明:海底管道受撞击部位的凹陷及损伤区域随着坠物能量的增加而增大;坠物形状因素由于碰撞发生时接触面不同对管道凹陷及损伤区域造成不同的影响;海底管道内压的存在一定程度上抵抗了碰撞造成的局部塑性损伤变形;轴向受拉对海底管道损伤方面的影响很小可忽略不计;适当增加轴向压力可提升海底管道抗碰撞冲击能力而过大的轴向压力会加剧管道破坏。

关键词(KeyWords)： 海底管道;坠物碰撞;凹陷;损伤区域;轴向预加荷载
