PURPOSE: An anchor assembly for ground stabilization is provided to maintain initial tensile force by preventing locker blocks from moving. CONSTITUTION: An anchor assembly for ground stabilization comprises a fixed block, multiple locker blocks(130), a moving block(120), elastic members(170) and a pulling block(140). The locker block adheres to the inner wall of a borehole. The moving block ascends and descends the locker block. The elastic members prevent the locker blocks from being separated from a plurality of guide passages of the fixed block. The pulling block horizontally moves the moving block.
