Based on the formation mechanism of preferential flow pathways in fractured rock masses and compiling useful programs, hydraulic properties of preferential flow pathways were briefly discussed and the stress-dependent properties were studied. The results indicated that the preferential flow pathways widely exist in interconnected fracture networks, dominant sets of joints or fractures and faults zone in fractured rock masses. Preferential flow pathways are remarkably correlative with the distribution of dominant sets of fractures and faults zone. According to the results, the water flow channeling and their distribution could be determined. Also, the rational recommendations were made for the design and construction in slope engineering and underground engineering.
