Large-scale shaking table tests are conducted to investigate the effects of non-liquefied crust overlying liquefied soils on an embedded footing. It is shown that (1) The total earth pressure before liquefaction is induced mainly by the inertial force of the building, (2) The total earth pressure after liquefaction is induced mainly by the soil deformation, (3) The relation between the relative displacement and the total earth pressure is linear before liquefaction. It becomes nonlinear with the development of pore-water pressure, (4) The maximum value of the total earth pressure corresponds to that predicted by the Mononobe-Okabe method.
