【摘要】 本文采用数值试验方法研究了岩石的非均质性对其强度及变形的影响。结果表明:当岩石的均质性越差时,岩石微观结构的细胞元的力学特性差异越大,岩石整体的力学特性较微观结构的细胞元的平均力学特性越小,岩石变形的非线性特征越明显;反之,岩石微观结构的细胞元的力学特性差异越小,岩石整体的力学特性越接近较微观结构的细胞元的平均力学特性,岩石的线性变形特征越明显。更多还原

【Abstract】 Studied tha influnce of rock inhomogeneity on intensity and deformation. Result indicate:The bigger difference of mechanics char-acteristic of rock microstructure is, the smaller mechanics characteristic of rock mass is than microstructure’s, the smaller characteristic of non-linearity deformation is. contrarily The smaller characteristic of rock microstructure is and mechanics characteristic of rock mass is on the vergeof microstructure’s, the more evident characteristic of linearity deformation is.更多还原
