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.

I thought, that I was sitting on the Ground on the Outside of my Wall, where I sat when the Storm blew after the Earthquake, and that I saw a Man descend from a great black Cloud, in a bright Flame of Fire, and light upon the Ground: He was all over as bright as a Flame, so that I could but just bear to look towards him; his Countenance was most inexpressibly dreadful, impossible for Words to describe; when he stepp'd upon the Ground with his Feet, I thought the Earth trembl'd, just as it had done before in the Earthquake, and all the Air look'd, to my Apprehension, as if it had been fill'd with Flashes of Fire.
