BEAM Method BEAM is a focused-electrical frequency domain induced polarization method. The principle of BEAM is based on sending a guard current through an enclosing electrode A1 and a monitoring current of same voltage sign through an 2D-sketch of guard 3D-finite elements calculated model of BEAMinner electrode and focused current focused current and voltage ahead of the face A0 which is therefore forced into the forefield ground.3D simulation of the BEAM focusing effect (ETH Zrich, Switzerland) 2004 GEOHYDRAULIK DATA 11.

BEAM Method Measuring parameters Resistances frequency-dependent: R(f1) = U(f1) / I0(f1)[Ohm], R(f2) = U(f2) / I0(f2)[Ohm]with U(f) constant voltage and I0(f) monitoring currentPercentage frequency effect (PFE): PFE = 100 x (R(f1) R(f2)) / R(f1) [%] with f1 < f2.Geological interpretation Rock mass classification based on PFE values for geotechnical assessmentPercentage Frequency Effect PFE is a petrophysical property relating to the ability of rock mass to store electrical energy Porosity Pn (karst-cavities, faults, fractures) is related to PFE: Pn ~ 1/PFE Water-bearing and/or airfilled high porosity-zones can store little electrical energy and therefore are identified by low PFE Sand, clay layers, piles, boulders, concrete etc. are characterized by typical PFE-anomalies which are reliable detected with BEAM method in real-time 2004 GEOHYDRAULIK DATA 13.
