Abstract
To clarify the relationship between groundwater flow tate and statistical distribution of fractures in Youngchun waterway tunnel, the fracture characteristics and fractal dimensions of groundwater flow section were evaluated. The flow rate of 84,465m$^3$/day was identified in fault, accounting for about 70 percent of the total How rate. The flow rate of 36,525m$^3$/day was identified in joint, accounting for about 30 percent of the total flow rate. The flow late in the NATM section of sedimentary rocks increased with the fractal dimensions. The fractal dimensions determined in fault or fracture zones show more positive relation with the flow rate than those in joint developed zones.
