The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.

The experimental results show that when TCAR is about 700 ℃ XN for limestone is maximum, and the optimum TCAR for dolomite is about 650℃. Although XN for limestone is much higher than dolomite, the difference of their YN is little when TCAR is in 650~700 ℃. And if TCAL is beyond 1050 ℃ XN for limestone decays sharply, but it is negligible to dolomite. XN for dolomite is far higher than limestone in the high TCAL. XN for limestone decreases with the particle size increasing, and there is an optimum particle size range with particle size increasing which XN for dolomite reaches maximum in. The particle size plays a more important role in limestone carbonation process than dolomite.
