Abstract
A general analytical model which describes the nonlinear, anisotropic, elastoplastic, stress-strain-strength properties of the soil skeleton when subjected to complicated three-dimensional loading paths is presented. A brief summary of the model’s basic principle is included and the constitutive equations are provided. It is shown that the model parameters required to characterize the behavior of any given soil can be derived entirely from the results of conventional soil tests. The procedure can be easily programmed. The model’s accuracy is evaluated by applying it to represent the behavior of a cohesive soil under undrained loading conditions for nonproportional stress paths. Implementation of the proposed formulation for solution of boundary value problems is discussed.
