摘　　要：文章介绍了高密度电法及微动技术,在详查区隧道开展微动测试工作,确定微动新方法的有效性和适宜性。沿勘探线布设高密度电法测量剖面,圈定岩溶异常并在重点区域开展微动探测工作,利用单点频散曲线获得拟速度V_(x)剖面,综合解译岩溶位置与实际钻孔揭露岩溶深度一致,且吻合度较高,验证了高密度电法联合微动探测方法在探测岩溶的有效性。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 V_(x) 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.
