摘要
In offshore engineering, the soft marine clay beneath an embankment may be subjected to anisotropic consolidation stress paths, which greatly affect its monotonic and post-cyclic shear behavior. In this study, the post-cyclic undrained shear behavior of anisotropically consolidated soft marine clay was investigated by conducting a series of monotonic and post-cyclic shear triaxial tests. First, the post-cyclic undrained shear behaviors, including the stress–strain, pore water pressure, and effective stress paths, were investigated by comparing the results of the monotonic tests. Then, the degradation of the post-cyclic undrained shear strength was analyzed. Finally, an empirical prediction model of the post-cyclic anisotropy strength was proposed based on the definition of equivalent overconsolidation.
