The dynamic characteristics of earth pressures during earthquakes that have been observed on the lateral sides of an embedded large-scale-shaking-table foundation are studied The observed results have shown that the earth pressures on the opposite sides of the foundation were generated in phase for relatively lower frequencies and tend to be out of phase for higher frequencies It was also detected that the earth pressures on the lateral sides of the foundation were strongly related to the horizontal velocity motions of the foundation for relatively lower frequencies and to the acceleration motions for higher frequencies The analyses for the earth pressures were conducted by use of a simple lumped-mass-system equivalently replaced for the lateral soil of two surface layers Fairly good agreement between the analyses and the observed results was presented
