Abstract

Abstract

For sandy seabed, seabed overall instability are always caused by the wave-induced seabed liquefaction, which will have serious impact on the stability of the structures (offshore wind turbines, oil platforms) upper the seabed. To control the influence of seabed liquefaction, large number of scholars have investigated the wave-induced layered seabed response and liquefaction suppression with analytical and numerical methods, while related experimental research are still in its infancy. To further improve the related test rule and data, the study used one-dimensional cylinder experimental equipment to study the sandy deposit response and liquefaction suppression under wave loading, and found that when replace part of the seabed as liquefied protective layer, seabed liquefaction would greatly suppressed; when the thickness of liquefied protective layer reach 10% , seabed liquefaction phenomenon would not occur.
