Schematization of constitutive models for geomaterials and coherent prediction of the deformation and failure on ground behaviors

On the basis of the past researches on constitutive modeling of geomaterials and its application to geo-engineering problems which have been done in our laboratory, a simple and sophisticated model which can describe uniquely various soil features in general stress systems is presented. Also, this model is applied to the analyses of various geotechnical problems. The present research enables the ration and coherent predictions from ground deformation to the failure, though practical predictions of the deformation and failure have been done separately.
