TY - JOUR N2 - The goal of this work is to compare different constitutive models in the nonlinear static characteristic analysis of asphalt concrete core dams. The Duncan E-μmodel, Duncan E-B model and double-yield-surface model are three major constitutive models in the nonlinear static prediction of earth-rockfill dam. In this paper, an earth-rockfill dam with asphalt concrete core-wall in an actual hydraulic engineering is employed to compare the three models. The finite element model of the core-wall dam is proposed. Nonlinear static analysis of the dam is carried out and the static characteristics are obtained to study the differences generated from different constitutive models. Numerical results show that both the stress extremum and the stress distribution of dam body with three different models are coincident one another. In the deformation analysis of dam body and core-wall, the maximum values of sedimentation with the Duncan E-μmodel and the Duncan E-B model, which are greater than the value with double-yield-surface model, are close to the practical test data though the deformation distributions with three models are in good agreement. But, the analysis results of core-wall stress with double-yield-surface model are proper and more reasonable than the other models.
