It has often been indicated that the prediction accuracy of horizontal displacement by finite element analysis is inferior to vertical displacement (settlement). In this study, a new constitutive equation of the natural clay deposit was proposed for the purpose of improving the prediction accuracy of ground deformation. Then, the applicability of the proposed model for K0-consolidation tests in a triaxial cell was examined and the finite element analysis using the field measurement data of the large scale embankment were carried out. As the result, it was proven that the proposed model appropriately reproduced the element behavior of natural clay deposit in comparison with Sekiguchi and Ohta's model. And, the proposed model can predict settlements and horizontal deformations of large scale embankments at the good accuracy.
