Study on Response of Seabed and Applicability of Stability Analysis Method under Wave Loading

Abstract

It was known that a part of clayey seabed show a remarkable reduction in water content, increase of shear strength and the washout of fine contents under strong waves. A series of wave loading tests was carried out and the stability analysis was adapted to evaluate the stability of the seabed. It was found that the occurrence of crack is clearly related the property change of seabed, and that the safety factor was calculated by the stability analysis of circle slide with the yield stress of seabed as the strength gave a good explanation on the instability of seabed.
