    • Abstract
  • Based on the theory of infinitesimalization of plastic elements and infinite series, the visco-elastoplastic constitutive model for remolded loess is established through the triaxial creep tests under loading and unloading conditions and verified by the dynamic triaxial test, and the corresponding parameter indexes are obtained. The research shows that the constitutive model can well describes the creep, static and dynamic characteristics of the remolded loess and it more reasonably explain the variation characteristics of rebound curve under unloading conditions. In addition, the processing method for the infinitesimalization of plastic elements makes up for the shortcomings that plastic deformation is not easy to describe in the previous visco-elastoplastic constitutive model. Compared with other visco-elastoplastic constitutive models, the proposed model is simpler and more widely used.
