Abstract
Earth structures with precasted arch culvert and Terre Armee wall have been constructed in many parts of Japan. However, in a seismically active area like Japan, there is a need to study the seismic and shaking characteristics of the said structure. In this research, shaking table tests under two directional shaking in a horizontal plane were conducted to examine the effects of the shaking conditions, i. e., between one direction and two directions, on the dynamic stresses that develop in a 3-hinge arch and on the displacement of Terre Armee wall. Furthermore, the effect of friction between the ground and arch or strips was examined. Based on the results, the factors which are necessary to evaluate the seismic stability of the said structure are confirmed.
