有限单元法是近年来迅速发展起来的一种数值分析方法,目前已广泛应用于各个工程领域,收效甚大。有限单元法应用于岩体力学虽然时间不长,但已显示出有宽广的前途。岩体是一种复杂的介质,岩体的变形和破坏特性在很大程度上受断层、节理裂隙等地质因素的影响,其应力应变关系呈现出非线性的特性。然而,如果所给定的原始数据可靠,对地质因素的影响及边界 Finite element method is a kind of numerical analysis method developed rapidly in recent years, has been widely used in various engineering fields, with great success. The application of finite element method to rock mechanics has shown a promising future although it is not a long time. Rock mass is a complex medium. The deformation and failure characteristics of rock mass are largely affected by the geological factors such as faults and joint fissures. The stress-strain relationship shows a nonlinear characteristic. However, if the given raw data is reliable, the impact on the geologic factors and the boundaries
