GROUND REINFORCEMENT STRUCTURE, BUILDING STRUCTURE, AND CONSTRUCTION METHOD FOR GROUND REINFORCEMENT STRUCTURE
PROBLEM TO BE SOLVED: To provide a ground reinforcement structure, a building structure, and a construction method for the ground reinforcement structure that desirably prevent or suppress a collapse of a constraining ground between sheet pile walls that face each other, even when an earthquake vibration has propagated or a soil pressure load has increased.SOLUTION: A ground reinforcement structure 100 includes sheet pile walls 10 installed to face each other with a ground in between, the sheet pile wall 10 having a plurality of sheet piles 12 linked in one direction, and an elastic body 20 disposed close to surfaces that face each other, the elastic body being more flexible than the sheet pile 12. A building structure 150 is supported on a ground reinforced by the ground reinforcement structure 100, and an occurrence of ground subsidence is being suppressed. A recommended construction method for the ground reinforcement structure includes an excavation step, a sheet pile insertion step, and an elastic body insertion step. The steps are repeated for configuring the ground reinforcement structure 100, by forming a first sheet pile wall 10 having a plurality of sheet piles 12 and an elastic body 20 disposed in a direction of extension of the wall, and installing a second sheet pile wall 10 keeping the elastic body 20 of the first sheet pile wall 10 inside, opposite the first sheet pile wall 10 with the ground in between.SELECTED DRAWING: Figure 1
【課題】地震振動が伝搬し、また土圧の負荷が増大した場合であっても、対向する矢板壁間に位置する拘束地盤の崩壊を良好に防止または抑制可能な地盤補強構造、建造物、および地盤補強構造構築方法を提供する。【解決手段】地盤補強構造１００は、一方方向に連係された複数の矢板１２を有する矢板壁１０が、地盤を介して対向して配置され、対向して配置された矢板壁１０が、対向面に沿って近傍に配置され矢板１２より柔軟な弾性体２０を備える。建造物１５０は、地盤補強構造１００により補強された地盤に支持されており、不等沈下の発生が抑制されている。推奨される地盤方向構造構築方法は、掘削工程、矢板挿入工程、および弾性体挿入工程、を有し、これらの工程を繰り返すことによって、一方方向に連係された複数の矢板１２を有し延在方向に沿って弾性体２０が配置された第一の矢板壁１２を形成し、第一の矢板壁１０の弾性体２０を内側にして、第二の矢板壁１０を、地盤を介して第一の矢板壁１０と対向させて地盤補強構造１００を形成する。【選択図】図１
