摘要: 本文首先论述了各种不同成因和地质时代黄土的应力-应变关系及其数学模式;然后探讨了黄土变形参数的特点和变化规律;最后对黄土地基沉降量计算问题作了分析,说明三轴压缩试验非线性弹性参数的增量计算法的合理性。Abstract: In this paper the behaviours and mathematical models of stress-strain relationships of loess during different period of formation are discribed. Then the behavious of deformation parameters of loess and their laws of variation are studyed. Finally, the results of the calculated settlement of loess foundation are analyzed and compared. The analyses indicate that the nonlinear elastic increament method of calculated settlement of loess foundation with parameters of triaxial test is reasonable.
