First, a liquefaction analysis was conducted to evaluate the effect of liquefaction countermeasure during the earthquake. Then, a consolidation analysis was conducted to evaluate ground deformation caused by dissipation of excess porewater pressure. To verify the effects of the countermeasure, the analysis results of the grid-type improved ground were compared with non-improved ground and chemical grouting improved ground. As a result, a deformation reducing effect equivalent to that of the chemical grouting improvement was obtained from the grid-type improvement. It was shown that the combination of the liquefaction analysis and consolidation analysis is useful for evaluating deformation of the ground improved by the grid-type improvement. Furthermore, the grid-type improvement with wide grid-spacing indicated an effect on reducing subsidence.
