AbstractLade's elastoplastic work-hardening model for cohesionless soils has been used in a deformation analysis. Two passive earth pressure tests were utilized to compare analytical and experimental results. The load-deformation response and distribution of normal stresses acting on a fully instrumented wall were predicted, but a new interpretation of the work-hardening rule was necessary in order to use the model in the solution of boundary value problems. Measured and calculated values were generally in agreement. The results indicate that the model has the potential to produce reliable predictions of the behaviour of soil structures under a wide range of loading conditions.
