GROUND IMPROVEMENT FOUNDATION STRUCTURE
To provide a ground improvement foundation structure that can efficiently reduce the vibrating of the superstructure due to the surface ground amplification of seismic motion.SOLUTION: The present invention is a ground improvement foundation structure constructed by an improved body in which the ground and a cement-based solidifying material are mixed and agitated. In short, by making the total cross-sectional area of a plurality of large-diameter improved bodies 2 10% -80%, which is the ratio to the total area when the lower ground of a building 3 is set to an improvement range 31, adjustments have been made to deviate a predominant eigenperiod of the improvement range from an eigenperiod of the building.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効率的に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る。要するに、複数が配置される太径改良体２の合計断面積が、建物３の下方地盤を改良範囲３１としたときの全体面積との割合となる改良率で10%−80%にすることで、改良範囲の卓越固有周期と建物の固有周期とを乖離させるように調整がされている。【選択図】図１
