PROBLEM TO BE SOLVED: To reduce time, labor and cost required for constructing a ground improving body by reducing the volume of a solidification improving body. SOLUTION: The ground improving body includes the solidification improving body 2 constructed in a soft layer 21 where a structure 10 is constructed, in a state of surrounding the structure 10, and steel members 5 provided on at least one of a structure side surface 3 of the solidification improving body 2 and a surface 4 opposite to the structure to contact the surface 3, 4 or to have a space and driven so that the lower ends reach a support layer 22 below the soft layer 21. Since the steel members 5 can resist sliding and rotating resistance of the soil improving body, the same degree of strength as what is composed of only the solidification improving body can be obtained even if reducing the depth and volume of the solidification improving body 2.
