摘要： PROBLEM TO BE SOLVED: To provide an economical liquefaction preventing structure which is constructed by laying a lattice wall body in a manner floating from a non-liquefied layer.
SOLUTION: The liquefaction preventing structure prevents liquefaction of the ground by forming the floating type lattice wall body 1 having upper and lower surfaces opened and formed like a lattice in plan, on a liquefied layer 2 deposited on the non-liquefied layer 3. Herein each side length of a lattice of the floating type lattice wall body 1 is set equal to 0.4 to 0.8 times a wall height t, and the floating type lattice wall body 1 is floated from the non-liquefied layer 3, which contributes to reduction of the wall height t of the floating type lattice wall body 1, to thereby achieve construction of the economical liquefaction preventing structure.

摘要： PROBLEM TO BE SOLVED: To provide a liquefaction countermeasure structure suppressing liquefaction of the ground with a liquefied layer deposited on a non-liquefied layer or suppressing ground deformation caused by liquefaction without costing a great deal.
SOLUTION: The liquefaction countermeasure structure applied to the ground with the liquefied layer 2 deposited on the non-liquefied layer 1 includes a soil improving body 3 constructed in a position, separated from the non-liquefied layer 1, in the liquefied layer. Since a grounding structure 4 grounded on or set into the non-liquefied layer 1 and allowing the soil improving body 3 to abut on the side face is constructed, a horizontal displacement difference from the soil improving body 3 is reduced even when the non-liquefied layer 1 is horizontally displaced by an earthquake. The shearing strain of a permanent liquefied layer 2A between the non-liquefied layer 1 and the soil improving body 3 is thereby suppressed, and liquefaction or ground deformation caused by liquefaction can be suppressed.

摘要： PROBLEM TO BE SOLVED: To obtain a soil improvement structure which can restrain shear deformation from being caused by vertical motion of ground inside an underground wall, and which can suppress the liquefaction of the ground.
SOLUTION: This soil improvement structure 10 includes: the underground wall 20 which surrounds the ground 12; a deformation inhibiting plate 22 which is arranged on soft ground 18, which is higher in rigidity than the soft ground 18, and which covers the inside of the underground wall 20; and a joint member 24 for filling the gap between an inner surface of the underground wall 20 and the deformation inhibiting plate 22. In this case, since a vertical load is transferred to the soft ground 18 via the deformation inhibiting plate 22 during earthquakes the effective stress of the upper layer of the soft ground 18 is increased to constrain the vertical motion of the soft ground 18. Additionally, since the rigidity of the surface layer of the soft ground 18 is enhanced than the soft ground 18 by the deformation inhibiting plate 22, a horizontal force is transferred to the underground wall 20 from the deformation inhibiting plate 22 via the joint member 24 during earthquakes. Consequently, the shear strength and liquefaction of the soft ground 18 can be suppressed.

摘要翻译：要解决的问题：获得能够抑制剪切变形由地下壁内的地面垂直运动引起的并且可以抑制地面液化的土壤改良结构。解决方案：该土壤改良结构10包括：围绕地面12的地下壁20; 变形抑制板22布置在软地面18上，刚性比软地面18高，并且覆盖地下壁20的内部; 以及用于填充地下壁20的内表面和变形抑制板22之间的间隙的接合构件24.在这种情况下，由于在地震期间通过变形抑制板22将垂直载荷传递到软地面18，所以有效软地面18的上层的应力被增加以约束软地面18的垂直运动。另外，由于软地面18的表面层的刚度比由软化地面18由变形抑制板22提高在地震期间，水平力经由接合构件24从变形抑制板22传递到地下壁20。因此，可以抑制软地面18的剪切强度和液化。版权所有（C）2010，JPO＆INPIT
