Zusammenfassung:PROBLEM TO BE SOLVED: To provide a low-cost and positive method for suppressing the deformation quantity of an earth retaining wall that can suppress the horizontal deformation of the earth retaining wall generated after excavation, to a small quantity. SOLUTION: Prior to the excavation of the ground 1 surrounded by the earth retaining wall 3, drillable vertical columnar intrusive bodies 9 are preferentially driven into the ground 1 near the earth retaining wall 1. Horizontal deformation equivalent to a part of horizontal deformation of the earth retaining wall 3 generated toward the excavated side after the excavation of the ground is thereby applied beforehand in a reverse direction. It is preferable that the columnar intrusive body 9 is a quick lime pile with swelling property.
