### Abstract

The uncertainty associated with the estimation of the in situ dynamic shear strength tau //R of a deposit with static shear stress acting at the plane of failure (anisotropic conditions) is the subject of this paper. Whether there is shear stress reversal or not, anisotropically consolidated samples strain progressively during cyclic loading. Because a cyclic anisotropically consolidated sample can fail before the pore water pressure reaches the confining pressure, the load cycles required to cause pore pressure equal to the confining pressure cannot be used as a parameter in the model of anisotropic shear strength. Considering all the failure criteria, the failure criterion proposed by C. S. Chang, et al. is considered here. The statistical model is developed in two steps: first, the cyclic shear strength tau //R is estimated in terms of the anisotropic strength parameter R//a under laboratory conditions; second, the laboratory relationship thus obtained is modified to represent in situ conditions.
