Electromagnetic Pulse Sounding for Geological Surveying with Application in Rock Mechanics and the Rapid Excavation Program

Abstract

A full scale version of an electromagnetic pulse sounding probe is described with attendant experimental data. Propagation and scattering measurements in limestone and dolomite media are presented. The scattering measurements are for targets consisting of faults, joints and lithologic contrasts in a dolomite medium. Measured frequency-dependent constitutive parameters for the limestone and dolomite media are given and realistic pulse propagation calculations using these data are shown. The basic problem of probe calibration is discussed and progress toward solution of this problem described.
