In this paper, the Element Free Galerkin Method (EFGM) has been used successfully to analyze the behavior of jointed rock mass. The penalty method has also been employed for the essential boundary condition. In the analysis of jointed rock mass using the mesh-based methods, specially when introducing joints, some dificulties, such as bad geometry, are encountered. The meshless methods, which only work with nodes, however, are free from the aforementioned problems.In this paper, in addition to the relative displacement of blocks, the displacements of joints and nodes of each block are calculated using the Element Free Galerkin Method. The comparison between the calculation time consumed by the EFGM and that for the Finite Difierence Method (FDM) has
shown that the former is less than that for the latter.
