LIQUEFACTION PREVENTION STRUCTURE FOR HOUSING GROUND
PROBLEM TO BE SOLVED: To provide a liquefaction prevention structure capable of preventing liquefaction of housing ground.SOLUTION: A liquefaction prevention structure comprises: a ground constraining wall 20 and a surface ground improvement body 30. A watertight structure is constructed in a gap between the ground constraining wall 20 and the surface ground improvement body 30. The ground constraining wall 20 is constructed as a floating type structure extended from a ground surface to a depth which does not reach a non-liquefaction layer 10b and has, at strategic positions thereof, either supporting column bodies 21, a supporting wall body with a plurality of supporting column bodies arranged in a row or steel pipe piles 23 which reach the non-liquefaction layer 10b.
【課題】宅地地盤の液状化を防止できる液状化防止構造を提供する。【解決手段】地盤拘束壁２０と表層地盤改良体３０とから構成される。前記地盤拘束壁２０と前記表層地盤改良体３０との隙間は水密構造に処理される。前記地盤拘束壁２０は、地表部から非液状化層１０ｂへは到達しない深さの浮き型構造として造成され、同地盤拘束壁２０の要所位置に、非液状化層１０ｂにまで到達させた支持用柱状体２１又は支持用柱状体を複数連ねた支持用壁状体若しくは鋼管杭２３を含む構成であることを特徴とする。【選択図】図１
