In traditional large strain analysis of roadbed consolidation

the constitutive relation with Jaumann stress rate is used

which can not consider neighborhood-deformation. In this paper

Truesdell stress rate considering not only rigid-body motion but also neighborhood-deformation was introduced into large strain consolidation （LSC） theory. Using both virtual work principle and Galerkin’s weighted residual method

the finite element formulations for LSC were derived

based on constitutive relations following objectivity principle. The corresponding plane-strain FEM programs were compiled and tested. The influences of Truesdell

Jaumann and simplified Jaumann stress rates on roadbed consolidation were mainly discussed. The results show that the settlement

lateral displacement and pore-water pressure calculated by traditional method are greater than those by the method based on the constitutive relation using Truesdell stress rate. The considerable magnitude of errors may occur for the case of using small-strain constitutive matrix

due to the dissatisfaction with objectivity principle. As far as common problems are concerned

the differences between the results by Jaumann or Truesdell stress rate could be neglected; and the traditional method is adequately accurate for the case of small deformation.
