英文摘要	In this study, based on the analysis of structural strength of loess, a new understanding of the structural properties of loess and the quantitative concepts of the bonding structural strength and the friction structural strength are proposed. Some new and accurate dynamic structural parameters of loess were suggested, such as the link structural dynamic strength potential parameter, the friction structural dynamic strength potential parameter, and the structural dynamic strength potential parameter. Dynamic torsional shear tests of loess were carried out to study the effect of soil structure on the soil dynamic characteristics, and the variation of dynamic structural parameters was analyzed. The dynamic constitutive relationship of intact loess was established with the structural parameters, and the effect of soil structure on dynamic soil characteristics was considered in this constitutive model. From the dynamic constitutive relationship, the maximum dynamic shear modulus and the maximum dynamic stress of intact loess can be obtained. This constitutive model can provide basic parameters and theoretical support for the stress-strain finite element dynamic calculation analysis of intact loess.
