摘　　要：隧道工程中常遇到众多不良地质现象,严重的会影响隧道安全施工问题。利用地质雷达对艾门坳隧道进行超前地质预报,验证了其对节理发育、裂隙水发育等不良地质现象有较好探测效果,为隧道的开挖和支护提供有效的依据。同时进行的监控量测及其数据分析,为判断围岩稳定性提供了有效途径。将两者相结合,相互印证,能为隧道动态施工提供有力保障。Many geological hazards might be encountered in tunnel excavations and some might adversely affect construction safety. This case history presents the prediction of geological conditions by using ground penetrating radar. Throughout con- struction, it is concluded that this method could reasonably detect the joints and groundwater in the rock mass in front of the excavation. This information provides bases for the excavation and support. Combining the prediction and the construction mo- nitoring results can provide an effective way to justify the stability of the rock mass and ensure a safe tunnel construction.
