Pullout Capacity Factor for Cylindrical Suction Caissons in Anisotropic Clays Based on Anisotropic Undrained Shear Failure Criterion

New plastic solutions of the pullout capacity factor for cylindrical suction caissons in anisotropic clays are presented this paper. These derived by employing lower bound and upper finite element limit analyses under an axisymmetric condition. In study, obey undrained shear (AUS) failure criterion with three strengths obtained from triaxial compression, extension, direct simple shear. The as a series design charts. effects dimensionless parameters, namely ratio depth to width caissons, adhesion factor, compression on demonstrated discussed. present can be used guidance geotechnical engineers caisson considering anisotropy clays.
