PROBLEM TO BE SOLVED: To provide a new slope stabilization method which allows for both of workability and slope stability effect.SOLUTION: One main anchor 1 is installed to be fixed to a support layer 2. A plurality of resistance support anchors 9 are installed around the main anchor 1, the resistance support anchors 9 having the tip of the anchor 9 remaining in an upper surface soil layer 3a. A reinforced soil mass is thus formed in the region where the resistance anchors 9 are installed in the upper surface soil layer 3a. The main anchor and the resistance support anchors around the main anchor are connected with connection members 6. The connection part composed of the connection members, the main anchor, and the resistance support anchors are in a connection mode which allows tensile force acting on the connection member to generate drawing force acting on the main anchor and the resistance support anchors so as to generate tensile force acting on each. The tensile force generated at the resistance support anchor is transmitted through the connection member to the main anchor, so that the main anchor is imparted with tensile force as reaction force. Consequently the reinforced soil mass in the region where the resistance anchors are installed in the upper surface soil layer 3a imparts bearing pressure force to a lower surface soil layer 3b.
