Application of EH4 Electromagnetic Method in Taihang Tunnel Survey
The Taihang Tunnel on an expressway in Shanxi has a complex geological situation,with a complex and diverse terrain,and the maximum buried depth is approximately 730 m,so general physical exploration methods are difficult to adapt to this tunnel.The EH4 magnetotall uric method system can meet the survey of the tunnel.Combined with the known geological conditions,the tunnel's 10 fault locations and 2 karst developing positions were successfully interpreted,and their water-rich situation and crushed surrounding rock situation were analyzed,providing a reliable basis for the classification of the tunnel's surrounding rock,delineation of the weathering layer,identification of water-rich location,and construction and a reference for investigating similar projects.
