Abstract
Seismic deformation method with earth pressure and sidewall friction acting on an embedded footing has been developed, to evaluate pile's stress during soil liquefaction. To verify the effectiveness of the proposed method, the dynamic centrifuge tests were conducted. The following conclusions were reached: (1) The bending moment at the pile head, estimated by the proposed method, showed good agreement with the centrifuge tests results; (2) The estimated amplitudes of the resultant force of earth pressure and sidewall friction, and the phase difference between the resultant force and the structure inertia force agreed well with the experimental results.
