Undrained cyclic torsional simple shear tests were conducted on sand samples reinforced with wires, copper plate, non-woven fabrics in order to apply reinforced earth method to liquefaction countermeasure method. In this paper, the effects of placing direction and stiffness of reinforced materials on the liquefaction resistance are investigated. Shown below are results of this tests.
i) Reinforcing effect is greater in case of putting materials to direction of principal stress.
ii) If reinforced materials are placed to the other direction, the reinforcing effect depends on the stiffness of reinforced materials.
