SHAO Sheng-jun1, LONG Ji-yong1, YANG Sheng1, et al. Analysis of structural deformation properties of collapsible loess[J]. 2006, (10): 1668-1672.DOI: 10.16285/j.rsm.2006.10.005.
Based on the stress-strain relation of structural loess
the structural parameter with the shear strain
water content and consolidation pressure is explored and described by a mathematical formula. The formula can give the curve between the structural parameter and axial strain with a peak-value in which the coefficients are also determined by the experiment results. Further the structural parameter is applied to analyze stress-strain behaviors; and a structural stress-strain relation is set up. The rationality of structural parameter and its stress-strain relation is verified by comparing the calculating curves by the formulas with the testing curves.
