Undrained Stability of Unsupported Conical Slopes in Anisotropic Clays Based on Anisotropic Undrained Shear Failure Criterion
https://orcid.org/http://orcid.org/0000-0002-1760-9838
In this paper, novel stability solutions of unsupported conical slopes in anisotropic clays are presented by using the lower bound and upper bound finite element limit analyses under an axisymmetric condition. The anisotropic undrained shear (AUS) model is employed in the analysis as a failure criterion for anisotropic clays. The parameters in this model consist of three anisotropic undrained shear strengths, which are directly obtained from triaxial compression, triaxial extension, and direct simple shear. The geometry of the unsupported conical slopes involves the height of the slope, the radius at the bottom of the slope, and the slope inclination angle. The stability solutions are based on the geometry and strengths of conical slopes in anisotropic clays, which are presented in the form of dimensionless design charts. The failure mechanisms of the unsupported conical slopes, where the influence of anisotropy is considered, are also demonstrated in the paper.
