Due to the pure and stable composition, direct reduction iron (DRI) is considered to be the perfect material for electric arc furnace (EAF) steelmaking. [1] As EAF steel output growing and the high quality scrap supply is seriously insufficient, the demand for DRI will grow continuously in the world.

China's steel production growth is mainly driven by the extensive production, especially small and medium-size steel companies who use a lot of iron ore for the production of crude steel, steel billets and other low-end products, which cause low profits, high energy consumption, pollution and raw material waste.

Because the stiffness and rigidity of materials used in the superstructure is great difference from the foundation soil stiffness, there exists very great difference among the deformation of foundation and structure, especially when the building uplift value is excessive, the structural deformation and internal forces will exceed the allowable value, or even destroying the building.
The Mohr-Coulomb constitutive model is induced in every soil layers, and the elastic constitutive model is adopted in the materials of slurry bubbles and preventing-grout wall.
