Application of TSP and Geological Radar in Advanced Geological Prediction of Karst Tunnel Engineering
In order to investigate the potential geological risks in the construction of karst tunnels and guide the safe construction of tunnels,TSP and geological radar are used to carry out advanced geological prediction.The TSP method can predict the distance of 100～150m in front of the tunnel,which is characterized by long predic-tion distance,rapid analysis of surrounding rock conditions,and uncontrollable prediction accuracy;The geolog-ical radar method can realize the accurate prediction of tunnels at short distance,which can effectively make up for the shortcomings of TSP method in short distance.The combination of the two methods can improve the accu-racy of the prediction conclusions of karst structures in tunnels.The application example of TSP method combined with geological radar method can provide a reference for the advanced geological prediction of surrounding rock tunnels with similar risks.
