Abstract：Since the traditional rock block index(RBI) cannot represent the spatial characteristics of the rock structure，a quantitative system integrating the evaluation index of rock structure at the tunnel axis direction and the tunnel radial direction based on RBI was built. A two-dimensional fracture model of the tunnel work face in tunnel project was established first based on the digital imaging，and the method of sampling line was employed to obtain RBI of 19 scan lines which were set on the model using the computer. The rose diagram of the RBI was also proposed in which the radius in each direction and the area of the rose reflect the RBI of the scan line and the comprehensive evaluation index of rock structure(called Z-RBI) on the working face. The six color classification of the rock structure by Z-RBI was presented，and the prediction method of the rock structure at the tunnel axis direction was also proposed and verified.
