| Abstract: | 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. |

| Keywords: | jointed rock adapitve finite element hadaptivity quadrilateral element mesh regeneration |
