摘要
基于Goodman节理单元的应力精度分析,本文提出了一种将节理视为内部应力边界的节理岩体自适应有限元分析方法,并且使用四边形单元和网格再生成法,实现了承受压剪作用的单一裂纹试件和一边坡工程问题的网格加密型(h型)自适应分析。
A method for the hadaptive finite element analysis of jointed rocks is suggestedin this paper,which is based on the precision analysis of the stress of Goodman joint element model and takes the joint as an interior stress boundary.A rock block with a singlejoint and subjected to compress and shear load,and an engineering slope are analyzed successfully, using the suggested method,quadrilateral element and mesh regeneration.
