Simulation of the constant water content triaxial shearing tests using elasto-plastic model

Abstract

    This paper presents the simulation results of the triaxial tests under the CW condition on compacted silt specimens at the maximum dry density and optimum water content. The theoretical framework for simulating of the triaxial tests under the CW condition was based on the elastoplastic model with the incorporation of soil­water characteristic curve (SWCC). The shear strength, excess pore­water pressure and volume change during shearing under the constant water content conditions were simulated using the proposed elasto­plastic model. The simulation results show the good agreement between the simulated using proposed equations and the experimental results.
