摘　　要：海洋构筑物的海底防冲刷是海洋工程亟需解决的问题。文章阐述了仿生水草海底防冲刷技术,该技术基于海洋仿生学原理,通过仿生水草对海流的黏滞阻尼作用,降低海流流速,促进泥沙淤积,从而解决了海底管道等构筑物的悬空、淘空等问题。该技术应用于埕岛油田海底管道悬空治理具有明显的促淤埋管效果,为河流及海底管道的悬空防护提供了新途径。Subsea scour prevention is the problem needed to solve for offshore structure. Bionic aquatic weed, an advanced technique based on bionics, can reduce the current velocity and accelerate sand deposit by the effect of viscosity resistance on sea current, and thus to solve the suspension problem of subsea pipeline. This technique has been used for the subsea pipeline at Chengdao Oilfield and obtained obvious effects of accelerating sand deposit and burying pipeline. It provides a new way to deal with pipeline suspension for other pipelines located in river or sea.
