摘　　要：介绍了瞬变电磁法(TEM)的原理、特点、工作方法和资料处理。该系统首次运用于云南省的高速公路深埋长隧道勘察中,结合其他手段,成功地解释出了隧道的岩性、地下水及断层破碎带的位置,为划分隧道围岩级别提供了较好的依据,同时也为高速公路深埋长隧道提供了一种新的勘察方法。The principle, characteristics, working methods and data analysis of Transient Electromagnetic Methods （TEM） are introduced based on the case study of its application to survey and investigation of the deeply-buried long tunnel in expressways in Yunnan Province. Rock property, underground water and the location of broken fractures with assistance of other technical methods are successfully explained, which provides the good basis for the classifying of surrounding rocks of the tunnel and a new method for surveying and investigation of deeply-buried long highway tunnels.

关 键 词：深埋长隧道 瞬变电磁法(TEM) 电法勘探
