The undrained strength of ko-consolidated clays sheared under plane strain condition is formulated as a function of the direction of the major principal stress on the basis of an elasto-plastic constitutive equation. The equation for the anisotropic undrained strength is applied to the theory of characteristic line field as well as to the conventional circular slip line method. The bearing capacity factor and the factors of safety of embankments at failure calculated based on the theory are shown together with the experimental and field data. Laboratory and field data are in good agreement with the theoretical values. For the covering abstract of the conference see IRRD 287689. (Author/TRRL)
