Abstract

Tunnel geological prediction of ground-penetrating radar waves propagation in a lossy inhomogeneous medium, there must be a high-frequency attenuation. We must consider the electrical energy and magnetic energy of the relaxation loss, while the tunnel surrounding the quality factor in determining the attenuation of the necessary elements. Three parameters are not independent of unrelated, but from a different side to reflect the attenuation. Considering the coupling effect between three parameters, culminating in the establishment of the radar electromagnetic waves attenuation coefficient, in inhomogeneous rock medium exists the presence of relaxation phenomenon. For the geological radar effectively identify the reflected wave with different properties, different absorption and attenuation characteristics to analyze and study the surrounding rock structures, are well ahead of geological forecast guidance tunneling significance.
