【摘要】 根据平面节理单元的各种类型的实用范围和各自的优缺点,系统介绍了平面节理单元的基本原理.给出了运用不同的节理单元对岩体中不同的不连续面进行模拟分析的实例,分析的结果表明只要确定了材料的本构模型,采用比较特殊的单元类型,仍然可以按照有限元的基本思想和步骤来对岩石类材料进行数值模拟,并可以取得较为满意的结果.更多还原

【Abstract】 According to the strongpoint and shortcoming of all kinds of plane joint elements and theirs applicable range,the basic theories of plane joint elements were introduced in brief.An example which utilized different plane joint elements to simulate the different sorts of discontinuity interface in rock mass was given,and the analysis result indicates that if only the constitutive model of a material is confirmed,and some special element types are adopted,with the basic principle and approach of the finite element to simulate rock materials,a more satisfactory result can be obtained.更多还原
