Abstract:CSAMT system is of electromagnetic auto collecting and analysis system. It has advantages both from MT and AMT. The Paper discusses the principle, characteristics, working methodology and data analysis of CSAMT. For the fist time this system is applied in surveying deeply-buried long tunnel in Expressway in Yunnan. Combined with other technical methods CSAMT successfully interprets the location of soft and weak layer, underground water and broken fractures. The CSAMT provides good rationale for the classifying of surrounding rocks of the tunnel. It is a new methodology for surveying and investigating deeply-buried long highway tunnels.
Keywords:CSAMT
