摘　　要：跨航路的海底管道主要遭受来自通航船舶抛锚及走锚的损伤风险,采用工程界常用的堆石保护法将显著增加挖沟及回填工程费用,增加油田开发成本.针对跨航路海底管道抗落锚、抗拖锚设计给出二维风险矩阵评估准则、损伤后果判定方法和失效频率的计算方法,通过计算实例分析锚重、混凝土配重层、埋深等敏感性参数对海管损伤后果的影响,并对如何降低风险提出建议,进而为工程设计提供一定参考.The subsea pipeline crossing fairways may be damaged by the dropping or dragging anchor of a ship. In this paper, the two-dimensional risk matrix for assessment of damage and calculation of failure frequency is presented. Through an engineering example and the calculation, sensitive parameters such as anchor weight, concrete weight coating, buried depth are analyzed. Suggestions for reducing risk are given, which provide certain reference to engineering design.
