摘要	Simplified numerical model is built according to centrifugal experimental results. The liquefaction degree and deformation of sand sediment around bucket foundation are simulated. Effects of main factors are investigated. A spring model for modeling the capacity degradation of bucket foundation is presented in which sand resistance is modeled by uncoupled, non-linear sand springs. When the liquefaction degree is 0.9 near the surface and is only 0.06 at the bottom of sand sediment, the capacity degradation of bucket is 12%, whereas it is 17% in centrifugal experiments. Deformation of sand sediment increases with the increase of loading amplitude and skeleton's elastic modulus and the decrease of frequent. The maximum vertical deformation on the surface of sediment is 0.25 times of bucket depth away from loading side. The maximum horizontal deformation is on the loading side.
