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. In the foundation in the inside region, a plurality of underground foundation improving bodies 2 formed into L-plane shapes, T-plane shapes and cross plane shapes are prepared separately from one another and dispersed. 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 hardener Reinforcing core materials 3 made of H-steel as stress materials are driven at prescribed intervals in the continuous underground wall 1.
