Abstract

Electrical resistivity prospecting has been recently increased in the application to tunnel, landslide and other investigations in the civil engineering field. Therefore, it is essential to establish the rock mass classification technique using electrical resistivity data. In this paper, the authors, try to propose a technique which can classify tunnel rock mass using seismic wave velocities derived from electrical resistivity data. In addition, the applicability of the proposed tunnel rock mass classification technique is discussed, by comparing estimated support patterns with actually performed ones.
