Abstract
Quantitative prediction of the damage of a heterogeneous earth structure induced by earthquake is very important However, any rational method for such a prediction has not been proposed yet. The soil as a material of the earth structure is generally heterogeneous. Therefore, a probablistic approach for the evaluation of the physical properties of the soil is advantageous. In this study, the residual settlement of a heterogeneous earth structure induced by earthquake is predicted based on the Monte Carlo simulation. The dynamic elasto-plastic finite element analysis is used in each calculation. In order to realize the reliability based design of an earth structure, a fundamental study such as introduced in this paper is indispensable.
