Fault, Water inflow, Water abundance degree, Groundwater dynamics methodAbstract
Water inflow is a common geological hazard in tunnel engineering. Particularly the tunnel sections located within fault zones are prone to severe water inflow. Taking the tunnel faults in Shantou City as a case, this study analyzes the topography, lithology, geological structure, and hydrogeological conditions of F1 and F7 faults. Based on the faults conditions, groundwater dynamics method was selected to calculate the water inflow into tunnel. The unit water inflow was used to classify water abundance at tunnel faults. The results show that the unit water inflow of F1 and F7 faults in tunnel exceeds 10.0 m²/d, indicating a strong rich in water. It is recommended to enhance preventive and drainage measures and improve advance geological forecasting.
