摘要
山西省某高速公路太行山隧道地质情况复杂,地形地貌复杂多样,最大埋深约730 m,一般物探方法难以适应,而EH4大地电磁法系统可以满足该隧道的勘察。文中简述了该方法的原理及特点,结合已知地质条件,成功解译出了该隧道的10处断层位置和2处岩溶发育位置,并分析了它们的富水情况及围岩破碎情况,为隧道围岩划分、划定风化层、富水位置及施工提供了可靠的依据,为类似项目的勘察提供了借鉴。
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.
