Large-scale shaking table tests are conducted to investigate phase difference between the inertial force of the super-structure and total earth pressure acting on the footing. It is shown that (1) The total earth pressure before liquefaction tends to be out of phase by 180 degrees with the inertial force, (2) The total earth pressure after liquefaction tends to be in phase with the inertial force, (3) Phase difference between the inertial force and total earth pressure can be estimated by considering the natural period of the super-structure, the predominant period of the ground, the ground displacement and the footing displacement.
