The calculated results show that the model considering both elastoplastic and anisotropic characteristics in determining soil stress strain relations agrees quite closely with the actual state.

In the test, after anisotropic consolidation, keeping the deviator stress, pore water is injected using pore water control apparatus under a constant volumetric strain controlled condition.

In view of the anisotropic damage characteristics of concrete under multiaxial stress state, an anisotropic elastoplastic damage model is presented.
