<p>PROBLEM TO BE SOLVED: To provide a liquefaction prevention structure capable of preventing liquefaction of housing ground.SOLUTION: A liquefaction prevention structure comprises: a ground constraining wall 20 and a surface ground improvement body 30. A watertight structure is constructed in a gap between the ground constraining wall 20 and the surface ground improvement body 30. The ground constraining wall 20 is constructed as a floating type structure extended from a ground surface to a depth which does not reach a non-liquefaction layer 10b and has, at strategic positions thereof, either supporting column bodies 21, a supporting wall body with a plurality of supporting column bodies arranged in a row or steel pipe piles 23 which reach the non-liquefaction layer 10b.</p> |
