As a foundation for deep-water floating offshore structures, the embedded plate anchor should withstand the complicated marine conditions involving the cyclic loads. The pull-out behaviors of the embedded plate anchor under cyclic loading must be considered whilst designing. This paper presents a numerical approach for assessing the cyclic pull-out behaviors of the embedded plate anchor based on a recently proposed anisotropic bounding surface plasticity model, which can capture the non-failure stable and degradation characteristics of saturated soft clay under cyclic loading with different stress-levels. The pull-out behaviors of the embedded plate anchor under both monotonic and cyclic loading are simulated and investigated. Effects of the mean value, the amplitude of the cyclic loading on the cyclic pull-out behaviors are analyzed. The results demonstrate that under different cyclic loading levels three typical types of the cyclic pull-out behaviors are obtained, i.e., the cyclic stable, the cyclic hypo-stable and the cyclic degradation.
