DEFORMATION SUPPRESSING STRUCTURE FOR EARTH RETAINING WALL AND DEFORMATION SUPPRESSING METHOD FOR EARTH RETAINING WALL
PROBLEM TO BE SOLVED: To provide a structure and a method for suppressing deformation of an earth retaining wall which are capable of efficiently suppressing the earth retaining wall from being deformed, even when there are restrictions in ground and site conditions upon applying a ground anchor construction method in timbering of the earth retaining wall.SOLUTION: A deformation suppressing structure of an earth retaining wall comprises: a soil improvement body constructed on the rear surface side of the earth retaining wall; and ground anchors whose anchorage bodies are anchored in the soil improvement body. The soil improvement body includes: vertical soil improvement walls each of whose one side end part is joined to the rear surface of the earth retaining wall; and a horizontal soil improvement wall that joins the neighboring vertical soil improvement walls. The plural ground anchors are installed so as to connect the earth retaining wall and an inner corner part of each joint part between the vertical soil improvement wall and the horizontal soil improvement wall. The vertical soil improvement wall is arranged at a position where one side end thereof faces an orthogonal member that is joined to the earth retaining wall on the excavation side, while interposing the earth retaining wall therebetween.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、効率よく山留め壁の変形を抑止することの可能な、山留め壁の変形抑止構造および山留め壁の変形抑止工法を提供する。【解決手段】山留め壁の変形抑止構造を、山留め壁の背面側に構築される地盤改良体と、地盤改良体に定着体が定着される地盤アンカーとにより構成し、地盤改良体が、一方の側端部を山留め壁の背面に接合させた縦方向地盤改良壁と、隣り合う該縦方向地盤改良壁を接合する横方向地盤改良壁とによりなり、地盤アンカーが、縦方向地盤改良壁と横方向地盤改良壁との接合部各々の入隅部と山留め壁とを連結するよう、複数設置され、縦方向地盤改良壁における一方の側端部が、山留め壁の掘削領域側に接合する直交部材と山留め壁を挟んで対向する位置に配置される。【選択図】図１
