摘　　要：地下管线探测技术具有多解性和局限性的特点,是产生系统误差的主要原因,物探方法试验与探测仪器的一致性校验是消除系统误差的主要方法。地下管线探测前,不但要对常用的电磁法技术进行方法试验,还要进行综合物探方法试验。对于仪器一致性校验,提倡采用总校点和分校点的工作模式。Underground pipeline detecting technologies have the characteristics of multi-solutions and limitation.The characteristics are the primary factors which cause systematic errors.The major methods to eliminate systematic errors are method tests of geophysical exploration and coherence checks of detecting apparatuses.Before underground pipeline detecting,the method tests are used in not only electromagnetic technologies but also general geophysical exploration methods.The working patterns of the head check spots and sub check spots are advocated when the coherence checks are carried out.

关 键 词：地下管线探测 系统误差 方法试验 一致性校验
