PROBLEM TO BE SOLVED: To provide a structure and a method for supporting an earth-retaining wall capable of efficiently supporting an earth-retaining wall when a ground anchor construction method is applied to a timbering of the earth-retaining wall, even when there are limitations with ground conditions and site conditions.SOLUTION: A deformation suppressing structure of an earth-retaining wall comprises an arm member connected on a rear surface side of a head part of each of a plurality of vertical members constituting the earth-retaining wall, a wale spanned to connect each of a plurality of the arm members, and a plurality of ground anchors of which a head part is anchored to the wale. An angular adjustment member is provided on the arm member for adjusting a top surface of the wale such that the top surface becomes a surface orthogonal to the ground anchor. The wale is installed on a top surface of the angular adjustment member.SELECTED DRAWING: Figure 1 【課題】山留め壁の支保工に地盤アンカー工法を適用するにあたり、地盤条件及び敷地条件に制約がある場合にも、効率よく山留め壁を支持することの可能な、山留め壁の支持構造および山留め壁の支持工法を提供する。【解決手段】山留め壁を構成する複数の鉛直部材各々の頭部であって背面側に接合されるアーム部材、複数の該アーム部材各々を連結するように架け渡される腹起し、および該腹起しに頭部を定着される複数の地盤アンカーよりなる、山留め壁の変形抑止構造であって、前記アーム部材上に、前記腹起しの上面を前記地盤アンカーと直交する面となるよう調整する角度調整部材が設置されており、該角度調整部材の上面に、前記腹起しが設置される。【選択図】図１
