摘　　要：在比较分析各种超前地质预报方法的基础上,提出了在公路隧道修建中岩溶的超前探测技术,即采用地质雷达、红外线探水法、超前水平钻孔、超前炮孔和掌子面地质素描相结合的方法,五种方法缺一不可。最后还提出了岩溶隧道突水的防治原则,供类似工程参考使用。Firstly,all kinds of geology predictions were studied.Then,the detecting technologies about Karst were put forward during building highway tunnel.This detecting method includes Geology Radar,Infrared Detecting Water,Horizontal Drilling Hole,Horizontal Shot Hole and Describing Geology at Excavating Face.Finally,prevention principles about water inflow were brought forward for Karst tunnel,which will be applied in similar Karst tunnels.
