摘    要:基于结构性黄土应力应变特性认识和大量试验结果的分析,揭示了黄土结构性参数与应变、含水率、固结压力之间的关系,并给出了结构性参数的数学表达式。将该式引入结构性黄土应力应变特性分析,提出了考虑结构性参数的应力-应变关系。分析计算所得的应力-应变关系与试验结果有较好的一致性,说明了原状黄土结构性参数描述的合理性和基于结构性参数应力-应变关系的合理性。

关 键 词:原状黄土  结构性参数  应力-应变关系

Abstract: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.
Keywords:original loess   structural parameter   stress-strain relation
