摘要
本文以复合材料弹性理论作了简要介绍，认为由多组非贯通节理切割的节理岩体可视为各向异性的弹性介质。将复合材料弹性理论应用于具有概率结构模型的节理岩体中，从宏观上考察了节理引起的岩体各向异性，推导了节理岩体各向异性的弹性短，提出了利用有限元计算弹性矩阵中应力比矩阵的方法，并对应力比矩阵的元素取值作了初步研究．
Abstract In this paper,the basic principle of the elasticity of composite materials is briefed,The rock mass cut by multiple sets of discontinuous joints may be regarded as an anisotropic elastic medium. Theory of the elasticity of composite materials is applied to the statistic jointed rock mass. The formula for anisotropic elastic matrix of the jointed rock mass is given. A method calculated the matrix of the stress ratio by the FEM is proposed and the value of element in the matrix of the stress ratio is studied.
