Paper Title:
The Research on the Viscoelasticity of Geogrid and Constitutive Model of Reinforced Soil
  Abstract

Based on the creep testing results of geogrids, a three-parameters viscoelastic constitutive model of the geogrids is established, and their applicabilities and reliabilities are evaluated by using the utmost optimization theory. It is illustrated that the three-parameters viscoelastic model of geogrids established can relatively accurately reflect the two-stage attenuation creep properties of geogrids at a low stress. Then, a constitutive model of reinforced soil considering viscoelasticity of geogrids is established, and the constitutive model parameters of reinforced soil are solved based on the utmost optimization theory. Finally, the variation regularities of stress-strain characteristics of reinforced soil with the changes of different influencing factors is studied.
