N2 - This paper investigates the effectiveness of non-coaxiality to deformation analysis. The deformation behavior of clay foundation under an embankment has been simulated with soil-water coupled finite element method, based on finite deformation using a non-coaxial Cam-clay model. Comparison with analytical results using the original Cam-clay model indicates that incorporating non-coaxiality into the Cam-clay model leads to marked shear deformation and large maximum shear strain under the embankment shoulder in earlier stage of embankment construction. The present analysis also gives acceptable results when compared with centrifuge model test performance. The deformation analysis using a non-coaxial model provides the appropriate evaluation of slope failures and more significant information for construction management of geotechnical projects in the early stage of constructions.
