LIQUEFACTION PREVENTION UNDERGROUND OBJECT AND SEISMIC GROUND DEFORMATION PREVENTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a liquefaction prevention underground object which is buried in the improvement object ground and achieves liquefaction prevention of the ground concurrently with reinforcement thereof in a such manner that reasonably improves excess pore water drainage performance and shear deformation prevention performance.SOLUTION: A liquefaction prevention underground object comprises: a plate-like body 2 which has a function to allow water in the ground G to permeate the same when excess pore water pressure is generated in the ground; a first water passage material 3 which is a vertical drainage channel fitted to the plate-like body 2 to drain permeated water in the plate-like body 2 out of the ground G; and a second water passage material 4 which is a water collection channel to collect and guide the water into the first water passage material 3.SELECTED DRAWING: Figure 1
【課題】改良対象となる地盤に埋設されてこの地盤の液状化の防止と地盤の補強とを同時に達成する地中埋設体について、その過剰間隙水の排水性能、及び、前記地盤のせん断変形を抑制する性能を、合理的に向上させる。【解決手段】地盤Ｇに過剰間隙水圧が生じたときに前記地盤Ｇ中の水を浸透させる機能を備えた板状主体２と、前記板状主体２に組み合わされて前記板状主体２に浸透された前記水の前記地盤Ｇ外への上下方向の排水経路を構成する第一通水材３と、前記第一通水材３に前記水を集め導く集水経路を構成する第二通水材４とを備えてなる。【選択図】図１
