摘　　要：根据红土山隧道地质特征,采用TGP206地质超前预报系统、地质雷达预报及钻探相结合的方法,对岩层破碎带进行地质超前预报;并对比分析了红土山隧道断层破碎带的预报成果与实际开挖围岩地质状况,验证了超前地质预报结果的准确性,说明超前地质预报在隧道施工中应用的必要性和多种预报手段结合的重要性。According to the geological characteristics of Hongtu Mountain tunnel,adopt TGP206 geological prediction systems,ground penetrating radar method and drilling forecast method to verify the rock crusher zone,contrast Hongtu Mountain tunnel forecasting the outcome of the fault fracture zone with the actual geological conditions of surrounding rock excavation to verify the results of advanced geological prediction accuracy,and proof the importance of the need for geological prediction in tunnel construction applications and a variety of forecasting methods combined.
