| 摘 要： | 较详细地考察了黄土结构性的研究现状,在三轴试验的基础上,提出了一个既能反映土粒微观排列的结构性,又能反映土粒间由于特殊的胶结结构而综合表现出的宏观力学特征,从而可以开展对土的结构性进行研究的结构性参数mσ。在分析大量试验数据的基础上,证明了结构性参数的合理性,灵敏性和稳定性,揭示了mσ与影响土结构性的因素之间的变化规律,使黄土的结构性定量化研究有了一个新的基础。

| Abstract: | This paper gives a detailed observation of the st ructural properties of intact loess. Based on the results of triaxial compression tests of intact lo ess, a quantitative parameter of structural properties, which can not only refle ct the microstructure and arrangement of the particles but also the microcosmic mec hanic characteristics due to the particular coherent structure of soil particle s, has been proposed to explore the structural properties of soil.At the same t ime ,based on the analysis of plentiful test results, not only the rationality, sens itivity and stability of the fabric index, but also the variat ion of quantitative parameter m&;#243; and the influence factors of so il structure have been revealed and verified.These works will provide a good fo undation for the deep research on the structural properties of loess. |
