In order to clarify the relation between a displacement of the wall and seismic earth pressure, horizontal vibrating tests are performed on sand or clay compacted in a box, 90cm in length, 58cm in width and 30cm in depth with a movable wall using the shaking table. The conclusions are summarized as follows : The vibrating earth pressures of sand and clay decrease with increase of a displacement of the wall. When a displacement of the wall becomes large, the phase difference between the vibrating earth pressure and the displacement of the wall becomes 180°. When the shear deformation of soil is relatively small, the amplitude of vibrating earth pressure-displacement of the wall relationship obtained by the experiment can be explained by the theory.
