摘要： 各向异性材料模型的一般计算方法需要编辑偏轴坐标系中的弹性矩阵,其推导过程十分复杂.针对这一问题,提出了一种基于FEM软件中两个坐标系(基本坐标系与辅助坐标系)的新方法.FEM软件自动转换两个坐标系的关系,因此该方法没必要编辑偏轴坐标系中的弹性矩阵,可简化各向异性模型的计算过程.计算结果很好地反映了各向异性材料的方向变化对巷道围岩应力分布的影响.

Abstract: The derivation of elastic strength matrix in partial coordinate system for anisotropic modelling is very difficult. To solve this problem, a new method was suggested on the basis of the two coordinate systems in FEM software. The FEM software converts automatically the relation between two coordinate systems, thus the derivation of elastic strength matrix in partial coordinate system is avoided, and the calculation process of the anisotropic model was simplified. The calculation results can reflect well the effect of the direction of anisotropic rock material on stress distribution of the tunnel.
