Application Research of Geology Exploration with EH4 Electromagnetic Image System in the Deeply-buried Long Tunnels |
| |
| Abstract: | EH4 electromagnetic image system is a kind of magnetotelluric sounding system that combines some controllable sources with natural sources. The geophysical methods can detect geophysical field continuously and get a lot of geoelectricinformation, it can finish the geological survey of the deep-buried long tunnels more quickly economically and high quality. This paper introduces the principle of this method in conjunction with the a highway tunnel in Southwest China Construction as an example, which shows that this method has the application effect in the division of geological structures and the identification of poor underground geological bodies and provides references for the subsequent tunnel and construction. |
