Transport Properties in Highly Fractured Rock Experiment. Phase 2 Tracer Tests inFracture Zone 2

摘要

A series of six groundwater tracer tests was conducted at AECL's UndergroundResearch Laboratory to investigate different groundwater tracer testing techniques and configurations for determining solute transport in a major low-dipping fracture zone within the granitic Lac du Bonnet batholith. The tracer tests were performed to compare two-well recirculating, non-recirculating and convergent flow tracer testing techniques; examine the effects of direction on the tests; examine the effects of different flow rates or pressure gradients; and compare the transport behavior of different tracers.
