PROBLEM TO BE SOLVED: To provide a method boosting liquefaction prevention effectiveness capable of suppressing an outside deformation of each improved wall by connecting both improved walls constructed in a cylindrical shape in the outer circumferential ground of a plurality of existing buildings independently standing in a row in a liquefaction prevention method of a foundation ground of each existing building constructed on the ground having a bare possibility of liquefaction such as a sandy ground or the like. SOLUTION: Cylindrical improved walls 4 surrounding the outer circumference of the foundation ground 2a of the existing building 1 are respectively constructed in the outer circumferential grounds 2 of a plurality of existing buildings 1 and, at the same time, the liquefaction prevention method of the existing building foundations standing in a row is so constituted that the adjoining improved walls 4 and 4 can be connected with tie walls 5 arranged at right angles to the improved walls 4.
