摘要： 在千枚岩隧道施工中，由于围岩软弱、破碎，在开挖过程中受扰动易出现失稳坍塌等地质灾害事故，严重威胁生命财产安全和工程质量，准确预报隧道地质情况，并做好防治预案，是控制和减少事故损失的前提。结合汶马高速鹧鸪山隧道K181+273～K181+376段的TSP超前地质预报成果与实际开挖结果跟踪对比，分析了TSP超前地质预报技术在变质岩区域隧道千枚岩段的应用状况，并且初步探讨了千枚岩隧道中的小型破碎带和千枚岩片理构造面对TSP超前地质预报技术的响应特征。

Abstract: In the phyllite rock tunnel construction，the soft, broken surrounding rock is easy to causing instability of the geological disasters such as collapse accident in the process of excavation disturbance. Tunnel geological disasters serious threat to life，property and engineering quality, Accurate prediction of tunnel geological conditions and make a good plan in prevention and control geological disasters is the premise to Control and reduce accident loss . This paper compared TSP geological forecast results with the actual excavation results for K181+273～K181+376 in Zhegushan tunnel Wenma highway. This paper also discusses the Tunnel Seismic Prediction (TSP) geological prediction technology application in phyllite section tunnel of the metamorphic rock area.
