PROBLEM TO BE SOLVED: To shorten a construction period and reduce a construction cost in a ground stabilizing construction method. SOLUTION: A strengthening body 10 having a hollow reinforcing member 11, a tension member 13 inserted in the reinforcing member 11, and a connecting head 12 projected from the outer surface of the reinforcing member 11 and connected to apply tensile force to the reinforcing member 11 when applying tensile force to the tension member 13, is inserted in an excavated hole H in the ground. The reinforcing member 11 is anchored to the ground by a solidifying material M filled between the excavated hole H and the outer surface of the reinforcing member, and the tension member 13 is tensed. In this tensed state, the head of the tension member 13 is anchored to a structure 3 disposed on the surface of the ground, to stabilize the ground.
