Application of TSP603 System in Advanced Geological Prediction of Railway Karst Tunnel
In order to improve the accuracy of karst prediction in tunnel construction and verify the application effect of new equipment in karst tunnel advance geological prediction,TSP603 system was applied in the advanced geological prediction of domestic railway karst tunnels.Some matters needing attention in the process of data collection and processing were given.The results obtained were combined with advanced horizontal drilling for comprehensive prediction analysis,it was inferred that there were 3 karst development sections in front of the palm.The results show that two methods are basically consistent in determining the development location of karst.Through later excavation and verification,the actual geological condition is basically consistent with the detection results.The research results indicate that the TSP603 system,as a new type of advanced geological prediction equipment,can improve the accuracy of karst prediction to a certain extent with its advantages of processing algorithm and multi-parameter interpretation,and can be extended to similar karst tunnel advanced geological prediction.However,it is still necessary to combine other geophysical methods to further verify the prediction effect of the system on karst caves and karst water.
