A modified three-dimensional plastic limit analysis method is proposed for lateral bearing capacity of the large-diameter pipe pile in the inhomogeneous and anisotropic soft ground. The bearing capacity is also numerically analyzed utilizing the FEM software ABAQUS
in which the soil is assumed to obey the Hill’s yield criterion. Both the failure mechanism assumed and the plastic limit analysis predictions are validated by numerical computations based on FEM. Through a parametric study
it is shown that the effect of soil strength anisotropy on the bearing capacity of the structure in inhomogeneous soil is smaller than that in homogeneous soft ground.
