摘　　要：在隧道施工过程中,隧道地质灾害点分布频繁且造成的施工风险很大。为保证施工安全,对掌子面前方的工程地质条件进行预测已经成为隧道施工中的必须工序。论文介绍了TRT和TST 2种超前预报技术的工作原理,并将2种技术应用于喇叭河隧道超前地质预报工程实践中。通过工程实例应用,2种预报技术均能够基本查明掌子面前方工程地质条件,同时2种技术又各具有不同优势。During the construction of the tunnel, the geological hazard points of the tunnel are frequently distributed and the construction risks are high. In order to ensure the safety of construction, predicting the engineering geological conditions in front of the face has become a necessary procedure in tunnel construction. This article introduces the working principles of TRT technology and TST technology, and applies the two technologies to the advanced geological forecast engineering practice of the Labahe river tunnel. Through engineering examples application, the two forecasting technologies can basically ascertain the engineering geological conditions in front of the face, and at the same time, the two technologies have different advantages.
