    摘要
  • 摘要: 采用同济大学的动态空心圆柱扭剪仪对福建标准砂干样进行了两个系列主应力轴单向旋转试验，研究了偏应力比与中主应力系数对主应力轴旋转条件下干砂变形特性及非共轴特性的影响。系列 I 保持平均应力和中主应力系数不变，进行不同偏应力比下的旋转试验；系列 II 保持平均应力和偏应力不变，进行改变中主应力系数的主应力轴旋转试验。结果表明：偏应力比与中主应力系数对干砂变形特性均有显著的影响。
    Abstract: Two groups of tests of unidirectional rotation of the principal stresses are conducted on dry Fujian standard sand by means of the dynamic hollow cylinder apparatus at Tongji University. The investigation highlights the influences of deviatoric stress ratio and intermediate stress parameter on deformation behaviors and non-coaxiality of dry sands. The mean stress and intermediate stress parameter are maintained as constant with a variation of deviatoric stress ratios in one test group, while the mean stress and deviatoric stress are maintained as constant with a variation of intermediate stress parameters in the other test group. The experimental results show that the deviatoric stress ratio and intermediate stress parameter have significant influences on deformation behaviors of dry sands.
