摘要
该文以唐山市二环路隧道勘察为例,针对该地区存在采空区和岩溶的地质情况,采用瞬变电磁法进行探测,查明了下穿隧道岩溶、采空区的分布情况,为工程设计和施工提供了可靠的地质资料。
In this paper,taking the investigation of the Second Ring Road Tunnel in Tangshan City as an example,aiming at the geological conditions of goaf and karst in this area,the distribution of karst and goaf in underpass tunnels is investigated by using transient electromagnetic method,which provides reliable geological data for engineering design and construction.
