PROBLEM TO BE SOLVED: To provide a liquefaction prevention method for feeding air into the ground, diffusing air in the object ground uniformly, and reducing the time required for feeding air. SOLUTION: A pipe for feeding air from on the ground is provided and extended in the ground, and an airtight material is provided on a surface part of the ground by covering it. Underground water is pumped up by the super well point method, and a peripheral region in the ground is put in a substantially vacuum condition to feed air into the ground through the pipe and then restore the underground water in the ground up to a natural underground water level.
