DISCUSSION ON QUANTITATIVE PARAMETERS OF LOESS STRUCTURE
Yonghong Li · Chinese journal of rock mechanics and engineering · 2011
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 me1,friction structural static strength potential parameter me2 and structural static strength potential parameter me) 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.
