FOUNDATION STRUCTURE FOR GROUND IMPROVEMENT
To provide a foundation structure for ground improvement capable of reducing vibration of an upper structure created by surface layer ground amplification of seismic ground motion.SOLUTION: A foundation structure for ground improvement constructed with an improvement body configured by mixing and stirring soil and cement-based solidification material is adjusted to separate a natural period of an upper structure from a predominant natural period of the supporting ground. The foundation structure for ground improvement is configured to be provided with a wall-like improvement body arranged to surround a lower ground of the upper structure and a plurality of columnar improvement bodies arranged on a horizontal place on which vertical load of the upper structure is applied.SELECTED DRAWING: Figure 1
【課題】地震動の表層地盤増幅による上部構造物の揺れを軽減させ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であって、支持地盤の卓越固有周期と上部構造物の固有周期とを乖離させるように調整がされている。ここで、地盤改良基礎構造は、上部構造物の下方地盤が囲まれるように設けられる壁状改良体と、上部構造物による鉛直荷重が作用する平面位置に設けられる複数の柱状改良体とを備えた構成とすることができる。【選択図】図１
