摘要
针对结构性黄土研究中的不足和存在的问题,以原状结构性黄土样和人工制备结构性黄土样 2 种试样的室内侧限压缩试验、等含水量三轴剪切试验和浸水变形试验以及等吸力三轴剪切试验为基础,研究了结构性黄土的湿陷及变形特性。结果表明,结构性黄土存在一个与广义应力路径无关的湿陷面,结构性黄土的变形与结构强度的破坏有直接的关系。
On the basis of a variety of tests on both the intact and artificial structural loess specimens including lateral confined compression test, iso-water-content shear test, triaxial immersion deformation test, and iso-suction triaxial shear test, the collapse and deformation properties of loess are comprehensively studied in the paper, for the purpose of overcoming some disadvantages existing in current studies of structural loess. The test results demonstrate that the structural loess has a collapse surface which is independent of the generalized stress path, and its deformation characteristic has close relation with the loss of structural strength.
