Comparison of the Hollow Cylinder and the Truly Triaxial Test Apparatuses for the Study of Anisotropic Clays.
Abstract
The test results presented and the discussion of the mechanism for development of shear strength make it clear that the undrained strength of anisotropic clays is dependent on both the magnitude and the direction of the principal stresses with respect to the principal material axes. The proper test system for investigation of the effects of anisotropy must be capable of applying relatively uniform and well-defined three-dimensional states of stress and strain, and have the ability to control the direction of the major principal stress axes relative to the principal material axes. The hollow cylinder apparatus and the truly triaxial apparatus, both of which were reviewed and evaluated in this report, are valid laboratory testing devices which, with few limitations, fulfill the stated requirements. The hollow cylinder apparatus applies different combinations of axial, spherical, and torsional stress to a relatively thin walled, cylindrical specimen. Interpretation of the stress and strain distributions requires the basic assumption that the specimen is a thin walled cylinder which behaves linear-elastically.
