摘要

Centrifugal experiments were carded out to investigate the responses of suction bucket foundations under horizontal and vertical dynamic loading. It is shown that when the loading amplitude is over a critical value, the sand at the upper part around the bucket is softened or even liq-uefied. The excess pore pressure decreases from the upper part to the lower part of the sand layer in the vertical direc-tion and decreases radially from the bucket's side wall in the horizontal direction. Large settlements of the bucket and the sand layer around the bucket are induced by dynamic load-ing. The dynamic responses of the bucket with smaller height (the same diameter) are heavier.
