海底管线防冲刷技术试验研究

An experimental scour-prevention technique for subsea pipelines

海底冲刷现象严重威胁着海底管线的安全运营.该文从海底管线冲刷机理入手,根据海底管线防冲刷技术的基本原理,提出了仿生防护措施——"人工草"固定法,并结合现有工程项目进行了试验研究,结果表明该方法可以有效地解决海底冲刷造成的管道悬空问题,为海底管线工程的设计、施工和维护提供了指导性的参考.

Sea floor scouring is the main threat to the safety of operational subsea pipelines. Fiber reinforced fixed mats were proposed as a kind of imitation vegetation that provides protection, based on scour mechanisms affecting subsea pipelines and the resulting fundamental principles of scour-prevention. An experiment was conducted with an existing pipeline project. It was shown that the suggested approach can effectively prevent the problem of scour induced suspended spans, providing a reference for the design, construction and protection of subsea pipelines.
