PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure construction method capable of being costlessly executed, preventing pore water pressure of the ground in the central part of a fill from rising and also securely preventing settlement of the fill. SOLUTION: In the liquefaction countermeasure construction method in a fill structure 1 for a railway/road, a shearing deformation restriction wall 2 is executed from the toe of slope of the fill structure toward the ground G, and drain pipe 5 or the like is provided so that the pipe slants from the toe of slope of the fill structure 1 to the ground G toward the substantially central part of the structure 1. In the vicinity of the shearing deformation restriction wall 2, a plurality of beam sections 4 or the like are formed along the depth direction of the shearing deformation restriction wall 2.
