Abstract
 Recently, a lattice-shaped cement treatment method has been used as liquefaction countermeasure. For generating a cost benefit of this method, the floating-type method, in which cement treatment is not extended down to a non-liquefiable stratum, has been proposed by the present authors. In this study, the floating-type method was applied for quay walls backfilled with liquefiable ground, and its effectiveness was examined by some physical model tests. The test results, such as displacement, response acceleration, and pore water pressure of model ground showed that the floating-type method was substantially effective as liquefaction countermeasure, although the fixed-type method was the most effective among the model tests.
