SUPPORT STRUCTURE OF EARTH RETAINING WALL
To provide a support structure of an earth retaining wall which can reduce a range of foundation improvement while securing required displacement suppression performance.SOLUTION: There is provided a support structure of an earth retaining wall on which a buttress-shaped foundation improvement part 2 is provided on a lower ground of an excavation bottom surface S. The foundation improvement part 2 includes a long part 21 which extends to a direction approximately vertical to a wall surface of the earth retaining wall 1, is provided adjacent to the earth retaining wall and is long in a depth direction, and a short part 22 provided adjacent to only the upper part of the long part. Here, the plurality of foundation improvement parts are arranged at intervals relevant to the width direction of the earth retaining wall.SELECTED DRAWING: Figure 1
【課題】必要とされる変位抑止性能を確保したうえで、地盤改良の範囲を低減することが可能な土留め壁の支持構造を提供する。【解決手段】掘削底面Ｓより下方地盤に控え壁状の地盤改良部２が設けられる土留め壁の支持構造である。そして、地盤改良部２は、土留め壁１の壁面に対して略直交する方向に延伸されるとともに、土留め壁に隣接して設けられる深度方向に長い長尺部２１と、長尺部の上部にのみ隣接して設けられる短尺部２２とを備えている。ここで、地盤改良部は、土留め壁の幅方向に対して間隔を置いて複数設けられる。【選択図】図１
