Dynamic risk prediction method of water inrush in tunnel.
| Dynamic prediction method | Primary dynamic prediction | Secondary dynamic prediction | Tertiary dynamic prediction |
| Risk level | I (extremely low-risk area) | II (low-risk area) | III (moderate-risk area) | IV (high-risk area) | V (extremely high-risk area) | Dynamic risk prediction methods | Geological analysis of the tunnel face; TSP or TRT detection | Geological analysis of the tunnel face; TSP or TRT detection; GPR or TEM or infrared water detection method | Geological analysis of the tunnel face; TSP or TRT detection; GPR or TEM or infrared water detection method; advanced drilling |
