| Abstract: | The high-frequency magneto telluric sounding method, EH4, is applied to the construction of Gaoershishan tunnel. By compared with the result from the drilling and geological survey, EH4 audio-frequency magneto telluric method has the ability of identifying the litho-logy, geological structure and the water content of rock at the macro level. In this paper we provide geophysical basis for the tunnel layout, design and construction. This is a good method to survey the cross-section of a deeply-buried long highway tunnels. |
