Abstract
A series of shaking table tests was conducted to investigate the performance of the cut-off sheet pile method as a liquefaction-countermeasure for underground structures. This method was found to be effective to reduce the uplift displacement of the structures. Especially, application of steel sheet piles with drain remarkably improved its effect. The mechanism of the uplift displacement under placement of the sheet piles was also demonstrated through test results. Simplified procedures were presented to estimate the deformation of the sheet pile wall and the uplift of the structure. Applicability of the proposed methods was discussed through comparison with results of the shaking table tests and centrifuge model tests.
