Abstract: As an important means of tunnel engineering geological exploration, TSP-3D advanced geological prediction technology realizes the accurate prediction of the surrounding rock conditions in front of the tunneling work through the principle of three-dimensional seismic wave reflection. This technology combines high-density data acquisition and 3D imaging analysis to effectively identify bad geological bodies such as fault fracture zones, karst development zones, and water-rich zones, and provides a scientific basis for tunnel construction under complex geological conditions. This paper focuses on the application of TSP-3D advanced geological forecasting in tunnel boring, and takes the Dian-Feng-Wu high-speed furnace tunnel under construction as a practical case, analyzes the radar image characteristics of rock mass fragmentation and water richness, and systematically analyzes the forecast data and verifies the results. The findings show that the system can forecast adverse geology with high accuracy, furnish reliable information for optimizing the construction scheme, reduce geologic hazards, and improve excavation efficiency, thereby playing a pivotal role in achieving the combined goals of safety and cost-effectiveness in tunnel projects.
