摘要
本文应用瞬变电磁仪对贵州省水盘高速大营脚隧道进行超前地质探测,准确预报其岩溶、富水地质段,并结合隧道内掌子面地质观察,对隧道初期支护参数提出修正建议,确保了隧道的安全施工。
In this paper,the TEM instrument is applied to do the geological exploration during the construction of Shui Pan highway dayingjiao tunnel in Guizhou province,and its karsts,water-rich geological section are predicted correctly.Combined with the geological observation of the tunnel working face,amendment proposals for the initial tunnel support parameters are provided to ensure the safety of tunnel construction.
