Abstract：The complexity and variety of rockmass structure are the very important reasons to induce variety of macroscopic deformation character of jointed rockmass. To evaluate the variety of rockmass structure，a correlation model is set up between deformation parameters and fractal dimension. The dimension is made as a measureable guideline to describe the rockmass structure in this model. Based on this model，the deformation character of surrounding rockmass is studied for a large-scale hydroelectric underground powerhouse.
