| Outline of Final Research Achievements |
It is ordinary assume that the shear box test is not suitable for measuring strain and density of sand because of the non-uniform deformation of the specimen. I assumed simple distribution of density in the sample at stead state, and using this assumption, I proposed a method for evaluating density-strength relationship at steady-state of sands. The validity of the method was confirmed from numerous shear box tests on various sands. X‐ray CT tests, triaxial tests as well as simple shear tests were done for the comparison purposes.
