Abstract;A wing-attached pile is proposed as a new concept of liquefaction remediation to expect a tranquilized lateral resistance even in a liquefying ground due to a strong earthquake motion. Elucidation of the proposed wing-pile with a pile-top displacement reduction effect is presented by showing results of a series of shaking table tests and comparing between a wing-pile and a normal pile. A reduction factor of pile top displacement of wing pile is studied related to magnitude of an input motion, density of ground, mass of pile top and cyclic mobility appearance. Magnitude of a reduction factor is about 0.8, which is same as a pile in compacted ground. (author abst.)
