Abstract EN
Nonlinear elastic model and elastoplastic model are two main kinds of constitutive models of soil, which are widely used in the numerical analyses of soil structure.
In this study, Duncan and Chang's EB model and the generalized plasticity model proposed by Pastor, Zienkiewicz, and Chan was discussed and applied to describe the stress-strain relationship of rockfill materials.
The two models were validated using the results of triaxial shear tests under different confining pressures.
The comparisons between the fittings of models and test data showed that the modified generalized plasticity model is capable of simulating the mechanical behaviours of rockfill materials.
The modified generalized plasticity model was implemented into a finite element code to carry out static analyses of a high earth-rockfill dam in China.
Nonlinear elastic analyses were also performed with Duncan and Chang's EB model in the same program framework.
The comparisons of FEM results and in situ monitoring data showed that the modified PZ-III model can give a better description of deformation of the earth-rockfill dam than Duncan and Chang’s EB model.
