SOFT GROUND SUPPORT STRUCTURE, AND CONSTRUCTION METHOD OF SOFT GROUND SUPPORT STRUCTURE

KASHIMATA AKIKO / NAGAYA KEIICHI / SAWARA MAMORU

To provide a soft ground support structure capable of allowing a tilt to support conditions of soft ground with different deformation amounts, and a construction method of soft ground support structure.SOLUTION: A soft ground support structure A1 includes: an embankment 21 around a building B1; a superstructure 40 that is connected to the building B1 on the embankment 21; and a ground improvement body 22 provided to a part of the embankment 21 below the superstructure 40 so that the deformation amount of the embankment 21 gets smaller as closer to the building B1.SELECTED DRAWING: Figure 1

【課題】軟弱地盤の変形量差がある支持条件に対して、傾斜を許容するための軟弱地盤対応構造及び軟弱地盤対応構造の施工方法を提供する。【解決手段】軟弱地盤対応構造Ａ１は、建物Ｂ１の周囲の盛土２１と、盛土２１上に、建物Ｂ１に接続する上部構造物４０と、建物Ｂ１に近い程、盛土２１の変形量が少なくなるように、上部構造物４０の下方に、盛土２１の一部に地盤改良体２２と、を設けた。【選択図】図１
