摘要 从锚泊作业引起的管道破坏入手,分析了不同锚泊作业情况下管道遭受锚泊撞击的失效概率。在对锚泊撞击计算模型和管道有限元动力分析的基础上,进一步阐述了当海底管道受到锚泊撞击风险时采取防护措施的必要性。提出的管道推荐挖埋方案,可为今后海底管道埋设深度研究及制定相关法律、规范提供技术参考。 Based on the damage of the pipeline induced by the anchor operation, the failure probability of the pipeline impacted by the anchor is introduced. Meanwhile, by employing the theoretical analysis and dynamic finite element method, it is pointed that taking the protective measures, when the pipeline is under the anchor impact risk, is of great necessity. The recommended plan for the burial depth of the pipeline can be regarded as the technological references for future establishment of the relative laws and rules.
