The dynamic earth pressure acting on the rigid caisson foundation was studied by the model vibration tests. The model caisson used in the experiment enabled to measure the dynamic earth pressure. In order to account for the characteristics of the dynamic earth pressure influenced by the backfill ground vubration, frequency of an input sinusoidal wave was chosen very wide. The fundamental information of the dynamic earth pressure with frequency, the effect of the caisson mass on the dynamic earth pressure, its phase difference from the inertia force of the caisson and its distribution, were given in this experiment. And authors also regarded the dynamic earth pressure as a variation from the static one during vibration and compared experimental results with the Mononobe]Okabe formula. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@@˜_•¶W
