摘　　要：本文论述了利用超级元法对不连续岩体进行数值分析的方法。超级元法把要进行分析的工程岩体划分成为数不多的若干个超级单元，每个超级单元中可以包括各种不同类型的结构单元，而总体刚度矩阵的规模大大减少，从而使得在大型岩体工程的分析中考虑各种类型的节理、裂隙的影响成为可能．This paper introduces the numerical analysis method of discontinuous rock to make the super finite element method.In this method the engineering rock that are needed to e are divided into a number of super element. Each of the super element can include s different types of structure elements.The scale of total stiffness matrix can be regreatly,so that it is possible to consider the influence of various types of joint,fracture lysing large engineering rock.
