タイトル（英）：	3-D LIQUEFACTION ANALYSIS TO EVALUATE THE STABILITY OF GRID-SHAPED STABILIZED GROUND BY DEEP MIXING METHOD
抄録（英）：	The present study shows the effects of the countermeasure against liquefaction using the grid-shaped stabilization by deep mixing method. The horizontal ground improved by 3 patterns of grid-shape stabilization is computed to evaluate the stability of the improved ground using a 3-D effective stress based liquefaction analysis code (LIQCA-3D). The grid-shaped improved walls receive the must of earthquake force and the sand surrounded with the walls behaves like a rigid body with the walls. The excess pore water pressure occurring in the sands surrounded with the grid-shaped improved walls during shaking becomes less than that in the unimproved ground. The mean effective stress, however, decreases to the very small stress level near by liquefaction region.
