摘要
本文基于岩体等不连续介质的实际结构特征建立了用于不连续介质力学分析的弹性体—夹层模型．该方法既能方便地求解连续介质力学问题，如岩体结构，另外由于在位移函数中已经将单元平动位移和转动位移同应变分离出来，因此很容易处理大位移、大转动问题．由弹性体—夹层模型可导出刚性有限元和弹性有限元的列式，而且块体的形状可以是任意多边形．
This paper establish elastrc-fault model for anlysis of discontinuous medium mechanics based on the actual structure feature such as rock mass and so on. The aboue method can solve questions of continuous medium mechanics as well as questions of large displacement and large rotation,because the translation displacement and the rotation displacement of element are separated from the strain in displacement function.Rigrd finite element formulas and elastic finite element formula can be derived conveniently by elastrc-fault model,and block shape may be any polygon.
