The excavation of deep buried karst tunnel will cause special damage and failure forms of the surrounding rock mass, and the damage zone will also affect the seepage field of the surrounding rock mass and the water inflow condition of the tunnel boundary. To understand the impact of blasting excavation on surrounding rock damage and seepage, a numerical model was created using COMSOL Multiphysics software. The model included a stress-seepage-damage coupling equation for calculations. The stress distribution of surrounding rock during tunnel excavation was calculated using both analytical and numerical methods. The results showed that there was consistency between the two methods. Large tensile stress was observed near the shoulder and foot of the tunnel due to the blasting load. Additionally, a tooth-shaped damage zone was formed in the water-resisting rock mass after blasting, leading to increased infiltration velocity in the shoulder and foot area, which can aid in determining the direction of the cave. Furthermore, changes in cave spacing and diameter, as well as water pressure, can influence the “tooth” extension angle, maximum water inflow position, and water inflow at the tunnel boundary. By considering the extension direction of the “teeth”, a reasonable position for detecting the damage zone can be determined. Moreover, adjustments in water inflow prevention measures and key prevention and control areas can be made based on changes in the maximum water inflow position and water inflow on the tunnel boundary.
