<P>PROBLEM TO BE SOLVED: To provide a method which improves earthquake resistance of subsoil by reinforcing a structure thereof in a manner that prevents microbubble from dissipating from an improvement object region when supplying the same with microbubble water and retains the microbubble in the improvement object region after supplying the same with the microbubble to maintain the improvement object region with a degree of saturation thereof reduced. <P>SOLUTION: A soil improvement method reduces a degree of saturation of subsoil by supplying the same with microbubble water. The soil improvement method: forms a dissipation prevention region, which prevents microbubble in the microbubble water from dissipating, outside an improvement object region to be improved by supplying the same with the microbubble water; supplies the improvement object region with the microbubble water; and retains the microbubble in the improvement object region by preventing the microbubble from dissipating with the dissipation prevention region. <P>COPYRIGHT: (C)2013,JPO&INPIT |
