Back Analysis of Treporti Test Embankment with a Time Dependent Small Strain Stiffness Constitutive Model

摘要：

　　This paper is concerned with back analysis of a trial embankment on soft soil.The analysis is conducted with and without consideration of small strain stiffness in the time dependent soft soil constitutive model.Whilst in loading during embankment construction small strain stiffness is found to be of minor importance,it is predominant in unloading.In unloading,the small strain enhanced model predicts deformations with considerably higher accuracy than its counterpart without small strain stiffness formulation.The time dependent small strain stiffness model is based on a recently proposed anisotropic creep framework and a strain space based small strain stiffness formulation.
