The results of a simple geotechnical benchmark problem, an embankment on soft clay, are presented and discussed. The problem has been simulated with several constitutive models: models that are commonly used for practical geotechnical engineering problems, as well as advanced models developed by SCMEP Network partners. These advanced constitutive models account for initial and induced anisotropy, destructuration and creep or combinations of these features. The comparisons highlight the effects of these features on soft clay response and demonstrate the differences between alternative constitutive modelling approaches.
