摘要
针对某高速公路隧道掌子面前方围岩情况及隧道拱顶上覆岩土体埋深特点,先采用TSP进行了长距离预测,又采用SIR-20地质雷达(配100m天线)进行了短距离验证,并采用Zond-12e地质雷达(配38m天线)对隧道拱顶上覆岩土体性状及分布情况进行了探测。3种物探方法的综合利用,有利地弥补了现有单种物探方法的不足,使探测结果对指导隧道施工更加科学合理。
According to the surrounding rock in front of heading and the burying characteristic of the soil above the tunnel arch of the right line of tunnel,TSP Tunnel Seismic Prediction system is firstly used to predict a long distance,then SIR-20 geology radar（to match the 100M antenna）is used to confirm,finally Zond-12e geology radar（to match the 38M antenna） is used to detect the soil characteristic and distribution above tunnel arch.With comprehensive utilization of the three kinds of methods,the insufficiency of a single method could be made up,and the survey result would be more scientific and reasonable.
