PROBLEM TO BE SOLVED: To suppress the prolongation of a predominant period of the soil caused by liquefaction of a liquefied weak stratum.SOLUTION: In a soil 10, a lattice-like soil improvement body 40 is formed as one example of a soil improvement body that imparts shear rigidity to an unliquefied weak stratum 10A and a liquefied weak stratum 10B. The lattice-like soil improvement body 40 has the upper part formed in the unliquefied weak stratum 10A and the lower part formed in the liquefied weak stratum 10B. In other words, the lattice-like soil improvement body 40 is formed across the unliquefied weak stratum 10A and the liquefied weak stratum 10B. |
