EARTH RETAINING WALL STRUCTURE AND CONSTRUCTION METHOD FOR EARTH RETAINING WALL STRUCTURE
To provide an earth retaining wall structure and a construction method for an earth retaining wall structure that can improve the rotation suppression effect of a buttress-type improvement body.SOLUTION: An earth retaining wall structure 1 is provided around an excavation area B of a ground A and comprises an earth retaining wall 11 provided on the boundary between the ground and the excavation area, a buttress-type improvement body 12 extending in a direction approximately perpendicular to the earth retaining wall in a plan view on the excavation area side of the earth retaining wall, and a base improvement body 13 connected to a lower end of the buttress-type improvement body. The buttress-type improvement body comprises a first improvement body 21 arranged so as to be in contact with the earth retaining wall, and a second improvement body 22 connected to the first improvement body and extending on the opposite side of the earth retaining wall. A bottom surface 22a of the second improvement body is located higher in the ground than a bottom surface 21a of the first improvement body, and the base improvement body is arranged so as to be in contact with the bottom surface of the second improvement body.SELECTED DRAWING: Figure 1
【課題】バットレス型改良体の回転抑止効果を向上することができる山留め壁構造および山留め壁構造の施工方法を提供する。【解決手段】地盤Ａの掘削領域Ｂの周囲に設ける山留め壁構造１において、地盤と掘削領域の境界に設けられた山留め壁１１と、山留め壁の掘削領域側に、山留め壁と平面視で略直交する方向に延びるバットレス型改良体１２と、バットレス型改良体の下端に連設される底盤改良体１３と、を備え、バットレス型改良体は、山留め壁に接するように配された第１改良体２１と、第１改良体に連設し山留め壁とは反対側に延設された第２改良体２２と、を備え、地盤内において、第１改良体の底面２１ａより第２改良体の底面２２ａの方が高い位置にあり、底盤改良体は、第２改良体の底面に接するように配されている。【選択図】図１
