摘要
超前钻探是隧道施工地质预报的重要手段之一。本文以高速公路隧道为工程背景，引入RPD-150C多功能快速钻机作为钻探机具，记录了钻速数据，并结合现场地质，分析得出了隧道前方围岩情况，以供隧道施工时参考。
Advanced dril ing is one of the important means of geological prediction in tunnel construction. in this paper, take the highway tunnel as the engineering background, the author introduced RPD-150C multi functioned drilling rig as dril ing tools, records the data of drilling speed, and combined with the geology, analyzes the front of the tunnel surrounding rock, for the tunnel construction of reference.
