Soft clays can be anisotropic in nature. In stability analysis of an undrained situation, one needs to account for the strength anisotropy. The chosen strength anisotropy factors refer to cuE/cuA and cuD/cuA must be site-specific and deduced from high quality soil samples. Here, cuA, cuE, and cuD refer to the undrained shear strengthobtained from active/compression (A), passive/extension (E), and direct shear (D)tests.
