Soil structure is the intrinsic determinants of its strength and deformation. Loess structure is determined by the link structural strength and the friction structural strength. Based on this

some new and reasonable structural parameters of loess are suggested based on soil static strength

such as the link structural static strength potential parameters

the friction structural static strength potential parameters and the structural static strength potential parameters . The variation of the structure and the structural parameters based on the static strength conditions are studied with the triaxial compression tests of intact loess and artificial cement structural loess; and the impacts of moisture content

confining pressure and axial deformation on the structure of intact loess and artificial cement structural loess are revealed. The results show that the water content of loess is smaller; its structure is stronger; and the greater loss of soil mass strength will occur after the structural damage. Loess structure damage mainly occurs in the small strain stage. Finally

the rationality of these structural parameters based on the static strength conditions are discussed.
