CONSTANT VOLUME DIRECT SIMPLE SHEAR BEHAVIOUR OF STATICALLY COMPACTED GRANULAR MATERIALS

Abstract

This paper describes the applicability of soil-water coupled analysis for simulating the constant volume direct simple shear behaviour of statically compacted granular materials. Multi-stage constant volume direct simple shear tests are carried out for investigating the consolidation and simple shear behaviour of granular materials. The constitutive model mainly employed in the calculations is an elasto-plastic model developed by Sekiguchi and Ohta (1977). The calculated results are compared with actual laboratory test data. The small strain behaviour of the constant volume direct simple shear is well correlated with calculated results.
