Abstract
New Loushanguan tunnel of Chongqing Guizhou railway is located in the karst and fault zone development section with strong water yield and complex engineering geological conditions. Through audio-frequency magnetotelluric(AMT) exploration, through data processing and two-dimensional inversion, the apparent resistivity profile of the tunnel is obtained. Combined with engineering geological data, the resistivity characteristics are analyzed, and the macroscopic lithology characteristics, karst development degree and fault fracture zone of the tunnel are explored the information of location and influence area provides geophysical basis for tunnel design and plays a guiding role in comprehensive geological investigation of deep tunnel.
