In order to investigate dynamic characteristics of earth pressure acting on underground walls of embedded structures, earth pressure and acceleration of a building and surrounding ground have been observed at an actual nuclear power plant site. From the observed results, correlation between dynamic earth pressure and seismic ground behavior is confirmed. Relative displacement between the building and ground corresponds well to dynamic earth pressure, and the dynamic earth pressure acts on a loading side on the underground wall. Acceleration responses and dynamic earth pressure calculated by 2-D FEM give good agreement with observed results. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
