Application of Sample Element Method to Determine the Mechanical Parameters of Blocky Structure Crack Rock Mass

Based on the analysis of the structure characteristics, influencing factor to the mechanical properties, the data of field surveys and indoor studies, the bolcky structure rock mass is classified and the relative sample element is built. The FEM is used to simulate the field large-size trail. The mechanical parameters of each sample element on the base of the mechanical parameters of block mass are abtained.
