摘要
以三峡翻坝高速公路项目天鹅岭隧道工程为例,介绍层析扫描成像技术(TRT)与快速钻探技术(采用RPD-150C多功能钻机)的综合地质预报应用,并对预报成果与应用效果进行分析。结果表明,两种技术的结合应用,可以更准确地预报岩溶隧道前方的不良地质体,并对围岩级别进行有效的划分,以指导安全施工的进行。
Taking Swan Mountain Tunnel of Fanba Expressway Project as example, the application of TRT and fast drilling （ multi-functional drilling rig model RPD-150C ） technology are expounded with the analysis of prediction effects. The results show that the two technologies predicted the harmful geologic bodies in front of the tunnel face and the surrounding rock grades can be classified effectively, which can guide the safety construction.
