Effects of Induced Anisotropies on Strength and Deformation Characteristics of Remolded Loess
Abstract In order to better explain the influence of induced anisotropy on the strength and deformation characteristics of loess, a complex stress path experiment of induced anisotropy of the remolded loess was carried out by using a hollow cylinder apparatus. Under the same condition of the intermediate principal stress coefficient b, the test carried out directional shear tests in the case of drainage. The effects and regularities of induced anisotropy on the strength and deformation properties of remolded loess were revealed. The results show that the remolded loess has obvious induced anisotropy, which cannot neglect the stress-strain relationship, strength and deformation of soil. The maximum difference in fail strength is 25% under different principal stress direction. Induced anisotropy has great influence on the stress-strain relationship of soil, which is the essence of soil properties. In some engineering practices, the result of stress-strain analysis of soil has great influence. Approximately isotropic remolded loess substantially eliminates inherent anisotropy. Therefore, this experiment will provide a good reference for the further study of soil anisotropy under complicated stress paths such as principal stress axis rotation.
