LIQUEFACTION PREVENTION STRUCTURE

PROBLEM TO BE SOLVED: To provide a liquefaction prevention structure extremely effective for liquefaction prevention. SOLUTION: A continuous underground wall 1 is prepared so as to surround the fixed range within a liquefaction foundation A and a plurality of underground foundation improving bodies 2 of prescribed widths and prescribed thickness are prepared so as to exist without being connected one another in the foundation A in the inside region. The underground foundation improving bodies 2 directing in different directions are prepared in dispersedly existing states so as to cope with stress of different directions. Both of the continuous underground wall 1 and the underground foundation improving bodies 2 are prepared by soil cement made of excavated soil and a caking material. H-steel as a reinforcing core member 3 is driven at prescribed intervals in the continuous underground wall 1.
