LIQUEFACTION COUNTERMEASURE METHOD
PROBLEM TO BE SOLVED: To continuously maintain an effective unsaturation state even in the ground near the ground surface, by making and retaining a required quantity of bubbles for continuously maintaining an unsaturation state (a saturation degree of about 90-95%) of this object ground in the object ground of a liquefaction countermeasure.SOLUTION: This method desaturates the object ground by entraining bubbles in the object ground, by agitating-mixing an AE agent used as a concrete admixture in the object ground of a liquefaction countermeasure while taking in air.
【課題】液状化対策の対象地盤中にこの対象地盤の不飽和状態（飽和度９０〜９５％程度）を持続的に確保するのに必要な量の気泡を作成、滞留させて、地表面近くの地盤中でも有効な不飽和状態を持続的に確保する。【解決手段】この工法では、液状化対策の対象地盤にコンクリート混和材料として用いられるＡＥ剤を空気を取り込みながら撹拌混合することにより、対象地盤中に気泡を連行して対象地盤を不飽和化する。【選択図】図１
