Abstract
One of the major considerations in the design of offshore structures is the effect of wave action on the foundation. This requires a study of the effects of cyclic loading on the soil properties. The anisotropic nature of clay soils, which results from sedimentation followed by K0 consolidation, plays an important role in its dynamic as well as its static behavior. An experimental program was undertaken to determine the trends in behavior of clays subjected to large strain cyclic loading. Thin long hollow cylinders of isotropic, and normally K0 consolidated and over consolidated clays, with varying degrees of anisotropy and differing stress-strain characteristics were cyclicly stressed at periods of 20 to 40 seconds using different levels of stress. Damping, modulus degradation, and increasing strain values are compared with stress, cycle number and consolidation pressure. Test results are fit to a well-known and widely used mathematical model.
