Numerical Simulations on Triaxial Strength of Silty Sand in Drained Conditions

Silty sand deposits exhibit low bearing capacity at different density levels and depths. It may be due to low frictional values and non-plastic behaviour in nature. This study focuses on response of silty sand under drained conditions of triaxial testing using hypoplastic model. The influence of soil state parameters i.e. void ratio/relative density, and consolidation pressure level on drained response of silty sands is examined from the model simulations. The model results are displayed graphically in terms of stress-strain curves, stress paths and volume change-strain plots. The results reveal that the response of soil is dependent on both the combination of density and consolidation pressure levels
