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. |
