Abstract

Abstract

Based on the Cam-clay model,the outstanding characteristics of the unified hardening model(UH model) are that the UH parameter is used to describe the stress dilatancy and the transformed stress tensors is used to exhibit the behaviour of clays in the three-dimensional stress space.The different models corresponding to the different soils are proposed modifying the hardening parameter appropriately.The UH model includes more than 10 models,which are the UH model for clays and sands,the UH model for overconsolidated clays,UH model for K_0 overconsolidated clays,the critical state model for sands dependent on stress and density,the model for soils with inherited anisotropy and so on.These models can describe the stress dilation/contraction,hardening/softening,overconsolidation,stress induced anisotropy,inherited anisotropy,creep,asymptotic state,rotational hardening,crushing under great stress and other characteristics of soils,respectively.
