Review on evaluations of anisotropic hydraulic properties in the fractured rock mass

Abstract Evaluating the hydraulic properties of fractured rock masses in the subsurface is crucial for geoengineering applications and mitigating geohazards. Understanding these properties around faults is particularly important due to their impact on fluid behavior. Various methods have been developed to evaluate formation permeability, including in situ tests on boreholes, laboratory tests on rock samples, and evaluations based on borehole logging data. This paper reviews previous studies on t
