GROUND IMPROVEMENT FOUNDATION STRUCTURE
To provide a ground improvement foundation structure capable of obtaining a rational and economical structure by defining a part for bearing a vertical load from a part disposed for restricting liquefaction.SOLUTION: A ground improvement foundation structure 1 is constructed of improvement bodies including subsoil and a cement-based solidification material which are mixed and stirred. The ground improvement foundation structure 1 includes: plural columnar improvement bodies 2, ... which are positioned in a plane on which a concentrated load P of an upper structure acts; and wall-like improvement bodies 3, ... which are formed between columnar improvement bodies so as to surround the lower subsoil of the upper structure. The depth of the columnar improvement bodies is deeper than the depth of the wall-like improvement bodies.SELECTED DRAWING: Figure 1
【課題】鉛直荷重を負担する部分と液状化抑制のために配置される部分とを明確にすることによって合理的かつ経済的な構造にすることが可能な地盤改良基礎構造を提供する。【解決手段】地盤とセメント系固化材とを混合撹拌させた改良体によって構築される地盤改良基礎構造１である。そして、上部構造物による集中荷重Ｐが作用する平面位置に設けられる複数の柱状改良体２，・・・と、上部構造物の下方地盤が囲まれるように柱状改良体間に設けられる壁状改良体３，・・・とを備えている。また、柱状改良体の深度は、壁状改良体の深度よりも深くなっている。【選択図】図１
