In this study, caissons for accelerating consolidation with many filtering-drains on their back sides, for the purpose of inducing lateral dissipation of excess pore water pressure caused by new backfill, have been proposed. And to analyze the effect of accelerating consolidation by using proposed caissons, the analytical solution for two-dimensional consolidation equation is derived. In an isotropic clay, this study shows consolidation times at ξ = 0.1 to reach the average degrees of consolidation of 50% and 90% when using caissons with drains are taken about 7 and 3.5 times less than those when using the conventional caissons, respectively.
