Abstract
This paper describes the stress field of characteristic-line method for anisotropically consolidated saturated clays under plane strain condition at failure state. The undrained shear strength under plane strain condition is obtained from the elasto-plastic constitutive model proposed by Sekiguchi & Ohta which can represent the stress induced anisotropy, and thus obtained shear strength in terms of effective stresses is employed in the theory of characteristic-line field as failure conditions. By solving the partial differntial equations with the pore water pressure as an explicit variable, we obtain the distributions of total stress, effective stress and pore water pressure at the failure state.
