Abstract: In this paper, an elasto-plastic model is proposed for soil with initially stress-induced anisotropy. T he hardening axis in the presented model is between the axes of the Cam-clay model and the Sekiguchi-Ohta model. A transformed stress based on the SMP criterion is used for making the model become a reasonable three-dimensional model. Comparisons with experimental data from drained shear tests on K0 normally consolidated clay in different stress paths show that the proposed model gives excellent predictions. Therefore, the model is more realistic than the Cam-clay model or the Sekiguchi-Ohta model in predicting the deformation and strength of soils.

Key words: elastoplastic model , K0-consolidation , anisotropy
