Abstract:
Laboratory techniques were developed that allow concurrent measurement of unsaturated matrix hydraulic conductivity and fracture transmissivity of fractured rock blocks. Two blocks of Apache Leap tuff containing natural fractures were removed from a site near Superior, Arizona, shaped into rectangular prisms, and instrumented in the laboratory. Porous ceramic plates provided solution to the top of the test blocks at regulated pressures. Infiltration tests were performed on both test blocks. Steady-state flow testing of the saturated first block allowed the determination of matrix hydraulic conductivity and fracture transmissivity. Fifteen cm of suction were applied to the top of the second block throughout an imbibition test. Analysis of infiltration into that block indicates that fracture flow at the low compressive stress applied during the test was minimal and matrix hydraulic conductivity at 15 cm of suction was an order of magnitude less than the saturated matrix hydraulic conductivity of the first block.
