摘　　要：简要介绍了隧道施工中超前地质预报的重要性,以及地质雷达超前地质预报的基本原理。以某隧道为例,采用多个天线的地质雷达对掌子面前方不良地质体进行探测,预报结果与现场开挖验证情况较为吻合,表明通过采用多个天线提高了对掌子面前方不良地质体探测的准确性。This thesis briefly introduces the importance of advance geological forecast of tunnel construction,and the basic principles of GPR prediction.Taking a tunnel for example,using GPR with two antennas in front of the tunnel face detection.The forecast results are consistent with the field verification of excavation.This means GPR with two antennas can improve the accuracy of advance geological forecast in front of the excavation tunnel face.

关 键 词：隧道 超前地质预报 地质雷达
