| Abstract: | 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. |
