摘要
将EH4高频大地电磁测深法应用于高原特长隧道—高尔寺山隧道构造、岩性的勘察,通过与钻探及地质调绘的资料对比,EH4音频大地电磁法可以在宏观上查明深埋隧道地层岩性分界、地质构造及其赋水性,为钻孔布置及隧道设计、施工提供地球物理依据,在高原地区深埋隧道勘查中能达到较为理想的效果。
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.
