In-situ soil is anisotropically consolidated at rest, and the coefficient of earth pressure at rest $K_0$ is dependent on the properties of soil and stress history. In order to estimate roughly the in-situ undrained shear strength of a $K_0$-anisotropically normally consolidated clay from isotropic consolidated undrained test, consolidated undrained shear testy with four different consolidation pressure ratios ($K={sigma}'_{3c}/{sigma}'_{1c}$) were performed and test results showed K-$alpha$ relationship, representing the strength ratio $alpha$ as ($S_u/{sigma}'_{1c})_{CKU}=alpha(S_u/{sigma}'_{1c})_{CIU}$. Strength ratio u increases with increasing consolidation pressure ratio. And the angle of internal friction $Phi'$and angle ratio $Phi'_{CKU}/Phi'_{CIU}/$ are increased with the increament of K-value.
