Experimental study of stress direction dependence of sand under biaxial rotation of principal stress
https://orcid.org/http://orcid.org/0000-0002-7624-1965
The principal stress rotation is often studied by considering the uniaxial rotation of principal stress. In this paper, the stress path on biaxial rotation of principal stresses is considered. The hollow cylindrical apparatus was used to achieve the principal stress rotation around the second stress principal axis. A novel specimen preparation device was developed, which was used to achieve the principal stress rotation around the third principal stress axis. The influence of principal stress biaxial rotation on the dense sand behavior was investigated under undrained conditions. The results revealed that the deformation properties of dense sand were closely associated with the stress direction dependence of the soil. An increase in the inherent anisotropy changed the slope of the effective stress path and the phase transition pore pressure, influenced the shear dilatancy and shear shrinkage characteristic of sand. Likewise, an increase in the stress-induced anisotropy changed the shape of the effective stress path, the development of pore pressure, the shear dilatancy and shear shrinkage characteristic of sand. More importantly, deformation properties of sand were affected by the coupling of the two factors, which was predominantly controlled by stress-induced anisotropy.
