Single parameter binary-medium model of fissured loess

  • 摘要: 为了研究裂隙黄土的结构和变形特性,在岩土破损力学理论框架基础上,把裂隙黄土视作由胶结块和软弱带组合而成的二元介质,将二元介质模型运用于裂隙黄土的研究。通过模型计算分析,得到裂隙黄土的单参数应力应变关系,并将其与三轴试验结果进行了对比分析。结果表明,将岩土材料二元介质模型应用于裂隙黄土特性的研究具有较好的适应性。 更多还原
    Abstract: On the basis of the theoretical framework of breakage mechanics for geo-material,the fissured loess can be regarded as a composite material consisting of bonded blocks and weakened bands,therefore,a fissured loess binary-medium model is formulated.Then the model will be applied to the study of fissured loess.By numerical calculation,the relationship of stress-strain can be obtained.A comparative analysis between the calculated results and triaxial tests is done.The results show that there is a good adaptability to apply the binary medium model to fissured loess.
