基于城市地下管线越来越多、越埋越深这一现状，本文根据低频电磁场探测基本原理，突破性提出了“竖直剖面法”的超深地下管线探测方法及工作思路。通过两个典型案例，成功探测深达27 m的超深管线和在复杂地面条件下准确辨别出深部管线。总结了“竖直剖面法”相对“水平剖面法”独特的超深地下管线优越性以及对探测超深地下管线的超高探测精度。

A growing number of underground pipeline are buried deeper and deeper in citys .In this situation ,how can we detect the supper deep underground pipeline accurately?Base on the principles of low frequency electromagnetic field detection ,this paper has made a breakthrough to proposed a detection method and work ideas named “the vertical section method” .Through two typical cases ,we have probed a 27 meters deep underground pipeline ,and accurately i-dentified the deep buried pipeline in a complex conditions of surface .Combined with “the horizontal section method”,it summarizes the unique advantages and high accuracy for detecting the deep buried pipeline of “the vertical section meth-od”.
