摘　　要：抛锚作业可能会撞击海底管道,对管道的安全运行造成威胁。文章分析了船舶抛锚作业撞击海底管道的能量、海管壁凹坑吸收的能量和海管保护层吸收的能量的计算方法,并给出了工程计算实例,得出不同锚重、埋深条件下海管的损坏等级,确定了合理的埋深,为海管安全敷设提供必要的参数。Anchoring job may impact submarine pipeline and imperil it.The calculation methods of impact energy to a submarine pipeline during ship anchoring job and the corresponding absorbed energy by pipeline deformation and pipeline protective layer are analyzed.Based on a practical calculation example,the damage grades in the conditions of different anchor weights and pipeline buried depths are obtained,the rational pipeline buried depth is determined.The results offer necessary parameters for safe pipeline laying operation.
