Abstract The structure of loess is determined by the link structural strength and friction structural strength between loess particles. To quantitatively describe loess structure is to quantitatively study the variation laws of link structural strength and friction structural strength of loess. Therefore，some new and reasonable structural parameters of the structural loess are suggested for different loading states，such as the loess structural parameters based on the deformation conditions(i.e. link structural deformation potential parameter mp1，friction structural deformation potential parameter mp2 and structural deformation potential parameter mp)，the loess static structural parameters based on the strength conditions(i.e. link structural static strength potential parameter mε1，friction structural static strength potential parameter mε2 and structural static strength potential parameter mε) and the loess dynamic structural parameters based on the strength conditions(i.e. link structural dynamic strength potential parameter mγd1，friction structural dynamic strength potential parameter mγd2 and structural dynamic strength potential parameter mγd). Moreover，the rationality，stability and wide applicability of the proposed structural parameters are discussed.

Key words： soil mechanics loess structural parameters structural deformation potential parameter structural static strength potential parameter structural dynamic strength potential parameter
