SUPPORT STRUCTURE FOR SOIL RETAIN WALL
To provide a support structure for a soil retain wall allowing necessary displacement suppression performance to be efficiently secured only by installing a widening part in part.SOLUTION: A support structure for a soil retain wall 1 is provided with a ground improvement part 2 in a buttress shape under the ground surface. The ground improvement part 2 extends in a direction generally orthogonal to a wall surface 11 of the soil retain wall 1, and widening parts 3A and 3B are formed at a middle part and an edge of the extending direction, respectively. The ground improvement part 2 is formed by continuously arranging column shaped improvement bodies 22 on a body part 21 extending in a direction generally orthogonal to the wall surface 11 of the soil retain wall 1, and the widening parts 3A and 3B are formed by column shaped improvement bodies 31 disposed to be adjacent to both sides of the body part 21.SELECTED DRAWING: Figure 1
【課題】部分的に拡幅部を設けるだけで、効率的に必要とされる変位抑止性能を確保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】地表面以下に控え壁状の地盤改良部２が設けられる土留め壁１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１１に対して略直交する方向に延伸されるとともに、延伸方向の途中及び端縁に拡幅部３Ａ，３Ｂが形成される。ここで、地盤改良部２は、土留め壁１の壁面１１に対して略直交する方向に延伸される本体部２１が柱状改良体２２を連続して設けることによって形成されるとともに、拡幅部３Ａ、３Ｂは、本体部２１の両側に隣接して設けられる柱状改良体３１によって形成される。【選択図】図１
