To study the liquefaction potential of sand surrounding bucket foundations, centrifuge experiments were carriedout. Results have shown that the sand layer around a bucket foundation softens or liquefies under vertical dynamicload when the load amplitude is over a critical value. The liquefaction potential decreased in horizontal direction from theside wall and in vertical direction from the surface of sand layer. The thickness of the completely liquefied sand layer increasedwith the increase of load amplitude. The affected area which has obvious liquefaction potential is almost the samefor a given bucket under different load amplitudes.
