Outline of Final Research Achievements

The present disign methods of geotechnical problems have been still based on the classic soil mechanics described in the textbooks published by Terzaghi and Peck and by Tayor in 1948. In these methods, the ground has been assumed to be different things depending on the problems to be solved.
The reason why the practical design methods have been remaining unchanged is that constitutive models which can describe the soil behaviior uniquely from the deformation and failure of ground in general stress systems have not been developed, regardless that advanced numerical methods become popular. In the present research, new design system in which the deformation and failure of various geotechnical problems can be analyzed in a uniform manneris presented, by extending and developing the research on constitutive modeling and its applications.
