摘    要:为了改善Goodman节理单元,M.Katona提出了不考虑刚度系数的摩擦──滑动节理模型.但是由于缺乏可行的数学分析方法,因而得不到真实可信的结果,特别是出现了节理面块体相互嵌入问题,影响了它的实际应用.本文采用了节点偶对分析方法,该方法是建立在几何力学约束边界的序列矢量判定的基础上,同时还可以顺利地解决节理交汇组合等复杂的岩体力学问题,并将该法应用于东江大坝监测分析之中,实测资料表明该法的计算结果令人满意.

关 键 词:节理模型,节点偶对分析方法,监测分析

Abstract:In order to improve Goodman Joint Model,a Friction-Sliding Model of Joints (FSMJ) has been proposed by M.Katona without having to use stiffness parameters (Kn,Ks).But it is difficult to obtain reliable results from FSMJ because of the mutual intrusion of solid elements at a common interface.A nodal coupling analysis method is suggested bassed on sequential vector determination of geometric constrained boundary. By using the proposed metnod, some complex problems in rock mechanics with combinative model of intersected joints can be successfully solved. The method has been applied to tile monitoring analysis of Dong Jing arch dam and the calculated results are satisfactory.
Keywords:joint model  nodal coupling analysis method  monitoring analysis
