Abstract
<p>When soil liquefaction is evaluated by numerical analysis, effective stress analysis is often used. In this paper, we propose a new method for estimating model parameters used in effective stress analysis. In our proposed method, liquefaction strength curves and pore water pressure curves obtained from laboratory tests are used as targets of the inverse analysis. It was confirmed that the parameters obtained by our method could not only reproduce both the liquefaction strength curve and the pore water pressure curve with high accuracy, but also the effective stress path, which was difficult by the existing method.</p>
