Strength criteria and slipping planes of anisotropic sand considering direction of major principal stress

Yantu gongcheng xuebao, 2018
The effect of directions of the principal stress on the deformation and strength of sand is due to the anisotropy of soils. The shear strength on a certain plane of the cross-isotropic sand is larger when the angle between this plane and the bedding ...
