To provide a support structure of an earth retaining wall that is applicable even when a gap between an earth retaining wall and a boundary line of a site on which the earth retaining wall is constructed is relatively narrow.SOLUTION: A support structure 12 comprises: tensioned ground anchors 20 that are arranged with intervals from each other along an earth retaining wall 10, extend vertically underground, and have heads 20a that protrude above the ground; and a plurality of metal fittings 22 arranged on the ground with intervals from each other along the earth retaining wall. Each metal fitting comprises: a first flat plate portion 24 being in contact with the ground surface and having one end and the other end; an inclined plate portion 26 extending diagonally upward from the first flat plate portion; and a second flat plate portion 28 provided with a hole. Each metal fitting is fastened to the head of the ground anchor at one end of the first flat plate portion, and is in contact with a head of a core material of the earth retaining wall at the other end of the first flat plate portion. The second flat plate portion surrounds the head of the core material of the earth retaining wall that passes through the hole, at the hole.SELECTED DRAWING: Figure 1
【課題】山留壁と該山留壁が造成される敷地の境界線との間の間隔が比較的狭い場合にあっても適用可能である山留壁の支持構造を提供すること。【解決手段】支持構造12は、山留壁10に沿って互いに間隔をおいて配置され地中を鉛直に伸びまた地上に突出する頭部16aを有する、緊張力を付与された地盤アンカー20と、地上に山留壁に沿って互いに間隔をおいて配置された複数の金具22とを備える。各金具は、地表面に接する、一端部及び他端部を有する第１の平板部２４と、第１の平板部から斜め上方へ伸びる傾斜板部２６と、孔が設けられた第２の平板部２８とからなる。各金具は第１の平板部の一端部において地盤アンカーの頭部に定着され、第１の平板部の他端部において山留壁の芯材の頭部に当接され、第２の平板部がその孔において該孔を貫通する前記山留壁の芯材の頭部の周囲を取り巻いている。【選択図】図１
