Description :
Fracture characteristics were investigated in 13 exposures in 5 study areas in weathered granite in eastern Asia. Two approaches were used to evaluate the field data : 1) joint spacings were tabulated and examined within each weathering grade (tabulated classification); and 2) each exposure was classified according to the dominant weathering grade (visual classification). Mean and median joint spacings and joint spacing frequency distributions were analyzed and compared statistically for each approach. The box fractal dimensions for joint spacing were calculated for exposures classified visually in each weathering grades.
