Application of high density electrical method combined with fretting technology in karst identification
This paper introduces the high-density electrical method and fretting technology,and carries out fretting test in tunnels in detailed investigation area to determine the effectiveness and suitability of the new fretting method.The high-density electrical survey profile is arranged along the exploration line,karst anomalies are delineated,and fretting detection work is carried out in key areas.The pseudo-velocity Vx profile is obtained by using single-point dispersion curve.The comprehensive interpretation of karst position is consistent with the actual karst depth exposed by drilling,and the coincidence degree is high,which verifies the effectiveness of high-density electrical method combined with fretting detection method in karst detection.
