The Application of Comprehensive Advanced Geological Prediction Method in Karst Tunnel
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.
