Abstract
<p>In this paper, we have examined the applicability of the log piling method, a liquefaction countermeasure, to shallow soil improvement. Three improvement cases with different liquefiable layer thicknesses all with the same improvement depth ratio of 0.58, and two unimproved cases with varying liquefiable layer thicknesses were tested using 1G shaking table in a laminar soil box. Excess pore water pressure ratios, settlement of structure model, and pile deformation after the tests were measured. Results show that even with the same improvement depth ratio, greater liquefiable layer thickness leads to smaller settlement and pile deformatoion.</p>
