ABSTRACT
The aim of this paper is to introduce strain-rate effects in practical FE-analyses of soft soil engineering problems. To this end the Soft-Soil-Creep model as currently available within the PLAXIS FE-code is briefly described. To account for the effect of principal stress rotation and induced anisotropy a new version of this model has been implemented by adopting the framework of multi-laminate type models. The performance of the different versions of the Soft-Soil-Creep model are compared by considering two practical applications. On choosing well documented test embankments, computational results can also be compared to reliable measurements. For the first test embankment, which is the well-known Boston trial embankment, the creep effects are shown to be small. In the case of the second trial embankment creep appears to be dominant.
