PROBLEM TO BE SOLVED: To provide a reinforcing method for a retaining wall capable of reinforcing the retaining wall having few amount of excavated soil without giving influence on a structure of the upper surface. SOLUTION: A hole is formed in the front of a foundation 11 of the retaining wall 1 to make a wide-flange shape steel as a core 21, and soldier beams 2 filling an excavated hole with a consolidated material mixed with cast-in-place concrete or excavated soil and cement are arranged every 2 m. The head section of the wide-flange shape steel is made to project 50 cm from the ground, concrete is placed between both soldier beams to form a link member, and the link member is combined with the foundation 11 of the retaining wall. Horizontal force going to move the retaining wall 1 in the horizontal direction by the back soil pressure is transferred to the soldier beam 2 from the foundation 11 of the retaining wall 1 through the link member 3, and horizontal resistant force of the retaining wall 1 is increased by making the soldier beam 2 resist the horizontal force.
