TECHNICAL NOTE. PRINTED CIRCUITS FOR STUDYING ROCK MASS PERMEABILITY

The purpose of this technical note is to describe an analog technique for studying the interconnection of joints, the equivalent flow path lengths and hence the permeability in any direction along a plane through a rock mass. The joint geometry, whether for a specific site or as a statistical simulation, is drawn as an array of joint traces. The drawing is translated directly into a printed circuit which allows the active network and equivalent pathlengths through the geometry in different directions to be established rapidly. The technique has several advantages including the fact that surface and underground excavation geometries can be simulated easily and different joint apertures can be modelled. (Author/TRRL)
