EH4在深埋长隧道地质勘探中的应用研究
|
摘要
EH4电磁成像系统是将部分可控源与天然源相结合的一种大地电磁测深系统,EH4能进行连续观测,获取丰富的地电信息,可以高效率、低成本、高质量完成隧道地质勘察任务。以西南某高速公路深埋长隧道施工为例,介绍EH4的原理,说明EH4在划分地质构造、查明地下不良地质体的应用效果,为隧道设计及安全施工提供参考。
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.
