SELF-REPAIRING TYPE GROUND IMPROVEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a ground improvement structure that uses a self-repairing type material at relatively fragile locations, in which the material contains blast furnace slug for exhibiting sufficient self-repairing capability and is mixed with reinforcing fibers for controlling the width of cracks.SOLUTION: A self-repairing type ground improvement structure comprises a ground improvement body comprising a plurality of first wall bodies 4A, 4B, ... arranged in a first direction and a plurality of second wall bodies 6A, 6B, ... arranged in a second direction that intersects with the first direction, and performing a liquefaction prevention function by dividing a target ground area into a plurality of blocks surrounded by the wall bodies. The ground improvement body contains a fragile part 10 of which the strength is relatively lower compared to the rest of the ground improvement areas. The fragile part is formed using the self-repairing type material, which is made by mixing reinforcing fibers into cement containing blast furnace slug.
【課題】自己修復性材料として高炉スラグを含むものを用いることで、十分な自己修復性能を発揮し得ることができ、補強用繊維を混入することでクラックの割れ幅を抑制でき、相対的に脆弱な箇所に当該材料を用いた地盤改良構造物を提供する【解決手段】 第１の方向に配列される複数の第１壁体４Ａ、４Ｂ…と、第１の方向と交差する第２の方向に配列される複数の第２壁体６Ａ、６Ｂ…とからなり、地盤対象領域を、それら各壁体で周囲を囲われる複数のブロックに分割して、液状化防止機能を発揮するようにした地盤改良体を有する自己修復型地盤改良構造物である。上記地盤改良体は、残りの地盤改良部分に比べて相対的に強度が弱い脆弱部分１０を含んでおり、この脆弱部分を、自己修復性材料を用いて形成し、この自己修復性材料は高炉スラグ含有セメントに補強用繊維を混入させてなる。【選択図】図１
