Abstract Soil structure is the intrinsic determinant of its strength and deformation. The structural property of loess is determined by the link structural strength and the friction structural strength. On this basis，some new and reasonable structural parameters of loess are suggested based on soil dynamic strength，such as the link structural dynamic strength potential parameter mgd1，the friction structural dynamic strength potential parameter mgd2 and the structural dynamic strength potential parameter mgd. The variation laws of structural property and the structural parameters based on the dynamic strength conditions are studied with the dynamic torsional shear test of intact loess；and the impact of moisture content，consolidation pressure and dynamic shear strain on the structural property of loess are revealed. Finally，the rationality of these structural parameters based on the dynamic strength conditions is discussed.

Key words： soil mechanics loess structural property link structural dynamic strength potential parameter friction structural dynamic strength potential parameter structural dynamic strength potential parameter
