摘　　要：岩溶隧道掘进过程中,隧道突水风险高,隧道突水灾害超前预报是一项必不可少的工作,同时也是隧道施工过程中的重点和难点。本文以某岩溶隧道为例,在隧道大、小里程方向分别开展TSP法超前地质预报工作,准确探测到了两处可溶岩与非可溶岩接触带的位置,进而为隧道圈定出高压富水岩溶区段。TSP法对突水灾害发生的位置进行准确预报,大大降低了施工风险,为后续施工提供了安全保障。In the process of karst tunnel excavation,the risk of water inrush is so high that advanced geological prediction of water inrush disasters in tunnel is essential and also a key and difficult task during tunnel construction.Taking a karst tunnel as an example,this paper carried out the advanced geological prediction via TSP in the direction of both large and small mileages of the tunnel.Through geophysical data analysis and interpretation,the contact zones between soluble and non-soluble rocks were detected accurately,allowing for delineation of the high-pressure and enriched water karst section in the tunnel.The TSP method accurately predicted the locations of water inrush disasters,which greatly reduced the risk of subsequent tunnel construction.
