A total stress-based bounding surface visco-elastoplastic model for soft clays is developed to accommodate multiaxial stress reversals. The model is constructed based on the dynamic triaxial tests of the model soil for the metro station structure shaking table model test

taking into account that the clays yield under very low stress level and present energy dissipation even the strain tending to zero under cyclic loading. The numerical simulation of the free field model test is performed based on the visco-elastoplastic model; and it is shown that the acceleration history of model soil is consistent with the results of the model test.
