The main purpose of this study is to form an evaluation method of the ground motion caused by an earthquake on the basis of the energy balance concept. The relationship between the ground settlement (volume strain) and the accumulate plastic strain energy should be investigated to conduct the proposed method for predicting the ground settlement. In this paper, it is demonstrated that the ground settlement is strongly dependent on the accumulate plastic strain energy through the cyclic undrained shear tests. Further, the simulation analysis of the shaking table test results with the large shear box and the simulation analysis of the actual seismic damage are conducted to discuss the applicability of the proposed method. From the simulation analyses results, it is confirmed that the proposed method can approximately predict the measurement value of the ground settlement that is the wide range value from 0 to 50 cm.
