摘　　要：在穿越航道的海底管道保护设计中，锚害是影响管道安全性的关键问题。论文分析研究了落锚的冲击能量以及回填埋设对冲击能量的吸收能力，锚在海床土壤里的拖曳轨迹，锚--土壤--堆石层--管道交互作用下拖曳轨迹。通过实例计算，验证了管道在设计埋深下的安全性。研究成果将为管道埋深设计提供一定的理论指导，对于保证管道安全和降低成本具有重要意义。Anchor damage has become a key issue for the protection design of subsea pipeline at shipping lanes. This paper conducts a study on impact energy of dropping anchor and absorption capacity of backfill, the anchor dragging trajectory in seabed soil, and the anchor dragging trajectory under anchor-soil-rock berm-pipeline interaction. The safety of subsea pipeline under the designed buried depth is verified with an example calculation. This paper will provide a theoretical instruction for buried depth design and has a remarkable meaning for pipeline safety and cost reduction.
