新型穿航道海底管道防锚保护方案试验及应用

介绍穿越航道海底管道常用的防落锚保护方式及一种新型柔性防护垫，并对比这些保护方式的应用特点。针对某项目实例，提出单一及组合防锚保护方式，并对此开展落锚撞击物理试验。基于试验数据和设计规范，评估落锚对海底管道强度的影响，并根据校核结论给出海底管道最优防护方案，为工程设计及海上施工提供依据。

Test and Application of New Protection Method Against Anchor for Subsea Pipeline Crossing Shipping Channels

The general protection methods against anchor dropping and a new type of flexible protective mattress for submarine pipeline crossing shipping channel are presented, and the application characteristics of these protection methods are compared. According to a project, the single and combined protection methods used to defense the failure from anchor dropping are proposed, and the test for the anchor dropping is carried out. Based on the test data and design code, the influence of anchor dropping on the strength of the submarine pipeline is evaluated, and the optimal protection scheme for the submarine pipeline is given according to the check results. The basis for engineering design and offshore construction is provided.
