Research on Bearing Characteristics of Gravity Anchor in Clay

The applications and studies of gravity anchors in the ocean are becoming more extensive. Most research, however, has been directed toward bearing properties sand. Relatively less attention paid to clay. Clay is widely distributed on seabed. research capacity clay great significance for offshore oil exploitation. Therefore, anchor was investigated by conducting reduced-scale model tests, process simulated through a 3D finite element method. Model tests numerical simulations were used determine curve V-H failure envelope simulation results test good agreement. form revealed analysis. effect cohesion, internal friction angle, mooring point height have studied. influence explored changing point. formula suitable different heights obtained.
