Normal stress‐induced permeability hysteresis of a fracture in a granite cylinder

The paper examines the influence of axial stress‐induced closure of a fracture on its permeability. The experiments were conducted on a cylinder of Barre Granite measuring 457 mm in diameter and 510 mm in height, containing a central cylindrical cavity of diameter 75 mm. Radial flow hydraulic pulse tests were conducted in a previous research investigation (Selvadurai et al ., PAGEOPH, 2005) to determine the permeability characteristics of the...
