摘　　要：目前公路隧道施工中,超前地质预报工作已纳入工序管理,根据隧道环境及特点,选择适宜的方法可有效提高预报效果。本文结合具体工程实例,介绍了TRT与地质雷达两种预报方法及原理,选取隧道代表性围岩地段,以掌子面地质分析为基础,进行了TRT地震波法与地质雷达法相结合的综合超前地质预报,通过对两种预报结果的比较分析,并与隧道实际开挖地质情况对比验证,结果表明两种方法结合可提高预报精度,对隧道信息化施工、灾害防治和安全保障具有重要作用。At present,geological prediction has been brought into the process management in highway tunnel construction.According to the tunnel environment and characteristics,appropriate methods can effectively improve the prediction effect.In this paper,TRT and geological radar are introduced based on a concrete engineering example.After representative wall rock sections of the tunnel are selected,based on geological analysis of the tunnel face,geological prediction is carried out using TRT seismic wave method and geological radar method.By comparing the two prediction results with the actual geological conditions of tunnel excavation,the results show that the two methods combined can improve the prediction accuracy,and play an important role in information-guided tunnel construction,hazard prevention and safety guarantee.
