The effect of faults and surrounding damaged rocks on hydraulic conductivity has been widely recognized, driven by changes in rock properties and grain size resulting from fault-related activities. This variability plays a crucial role in regional groundwater flow, especially in applications like radioactive waste disposal and geological storage of carbon dioxide. In this study, we investigate the effects of micro- and macroscopic fractures of granite samples on elastic wave velocity and hydraulic conductivity using samples from the Tanakura fault and analog samples. In the analog samples of the fault comprised granite samples with micro-fractures, macro-fractures, and fracture filled with mineral veins, which were simulated by thermal treatment, split tensile testing, and resin impregnation, respectively. The test results show the effects of confining pressure and fracture damage level on the hydraulic conductivity of the rock samples. We discuss the clogging effect of the fracture on the hydraulic conductivity which may depend on the fracture damage level.
