摘　　要：隧道施工过程中存在众多不良地质体,喀斯特地区隧道不良地质体常常出现涌水、涌泥、涌沙、地下暗河、溶洞等地质灾害,给隧道施工人员和机械设备造成巨大的危害。然而喀斯特隧道成灾不良地质体的预报难度非常大,单一的预报方式很难进行定性和定量预测。文章主要论述了综合超前地质预报方法在喀斯特隧道中的应用,包括地质调查法、地质超前预报、地质雷达、超前钻探。结果表明:综合超前地质预报可以较准确地预测掌子面前方喀斯特的发育和分布情况,有效降低施工风险,为不良地质的处置和设计变更提供可靠依据。There are many adverse geological bodies in the process of tunnel construction.Geological disasters such as water gushing,mud gushing,sand gushing,underground river and karst cave often occur in the adverse geological bodies of tunnels in karst areas,which cause great harm to tunnel construction personnel and mechanical equipment.However,the prediction of adverse geological bodies causing disaster in karst tunnels is very difficult,and it is difficult to make qualitative and quantitative predictions by a single prediction method.This paper mainly discusses the application of comprehensive advanced geological prediction method in karst tunnel,including geological survey method,geological advanced prediction,ground penetrating radar,and advance drilling.The results show that the comprehensive advanced geological prediction can accurately predict the development and distribution of karst in front of the tunnel face,effectively reduce the construction risk,and provide a reliable basis for the disposal and design change of adverse geology.
