Study on Risk Evaluation Method of Water Inrush and Integrated Geological Prediction Technology in High-Risk Karst Tunnel
Tunnel constructions often encounter unforeseen disasters, such as water inrush, bursting mud and some other geological hazards, which cause great casualties, economic losses and environmental destruction. Taking one karst tunnel as an example, through applying the supplemental geology survey and geology analysis, the karst development law is discussed. The risk evaluation system with 4 ranks about karst tunnel is put forward. Main control factors of risk such as formation lithology, geological structure and underground water etc. were synthetically considered. Based on the risk rank, and according to applicable scope, merits and drawbacks of different geological prediction methods, integrated advanced geological prediction methods, was put forward to the prediction of water inrush, mad flush. A multi-step warning and prediction system was established, and it included macroscopic, long-term, short-term geological prediction methods and geological precursory prediction methods. The advanced forecasting program was designed for different parts with different ranks, and the disaster prevention measures were made with the prediction results. The integrated advanced geological prediction methods were applied successfully in karst tunnels.
