Abstract
The settlement of the oil storage tank during liquefaction, is the most serious problem for the engineers and company owners. In this paper, one of liquefaction-resistant methods which constrain the soil under the oil tank by a sheet pile wall is used. Some series of model tests using centrifuge are carried out to evaluate the liquefaction-resistant method from a settlement point of view. The effects of the sheet pile wall and mass of an oil tank are tested, respectively. The results show that the settlements of the oil tank depend on the mass of the oil tank, and on the type of sheet pile wall, and also show that the closed type wall is more useful against liquefaction than the open type wall.
