Shaking table test was performed to investigate the appropriate liquefaction remediation area in the backfill behind a quay-wall in the application of the so-called Permeating Grouting Method. In the model test, the 1/40 scale model quay-wall was used and the base acceleration was applied in stages up to 400Gal. Seven types of remediation area were made in a tank and the difference of effect was compared with each others in terms of permanent lateral displacement and earth pressure acting on the caisson. The existing design method on the basis of seismic coefficient method was experimentally found to provide a considerably conservative side so that the design method was to be re-evaluate to revise in the way of more rational direction.
