GROUND IMPROVEMENT BODY
To obtain a ground improvement body that can reduce the lateral displacement of a liquefied layer and the sinkage of a structure.SOLUTION: A ground improvement body 30 has vertical walls 32, intersection walls 34, and sloping walls 36. The vertical walls 32 are constructed in a liquefied layer 12 along an edge 20C of an embankment 20 constructed above the liquefied layer 12. The plurality of intersection walls 34 are constructed at intervals in a direction intersecting the vertical wall 32, and each include a sloping part 34A with a downward gradient from an upper end of the vertical wall 32 toward a lower side of the embankment 20. The sloping wall 36 is constructed so as to connect the adjacent sloping parts 34A from the upper end of the vertical wall 32, and constituting a wedge-shaped ground improvement part 40 as a wedge-shaped part together with the vertical wall 32 and the intersection walls 34.SELECTED DRAWING: Figure 3
【課題】液状化層の側方変位を低減し、構造物の沈下を低減することができる地盤改良体を得る。【解決手段】地盤改良体３０は、液状化層１２の上方に構築された盛土２０の縁部２０Ｃに沿って、液状化層１２に構築された縦壁部３２と、縦壁部３２と交差する方向に間隔をあけて複数構築され、縦壁部３２の上端部から盛土２０の下方側に向かって下り勾配となる傾斜部３４Ａを備えた交差壁部３４と、縦壁部３２の上端部から隣り合う傾斜部３４Ａを繋ぐように構築されると共に、縦壁部３２と交差壁部３４とで楔型部としての楔型地盤改良部４０を構成する傾斜壁部３６と、を有する。【選択図】図３
