Study on Water Inflow Prediction of Operating Tunnel in Karst Trough Valley Area
Tunnel gushing not only affects the tunnel construction, but also will affect the safety and stability of the tunnel after operation. In this paper, Nanshan Tunnel is taken as an example to introduce the drainage of operating tunnels in karst trough area and to forecast and evaluate the drainage of operating tunnels. The main conclusions are as follows: (1) It is very meaningful to study the gushing water in the karst trough area by collecting a large amount of data of the gushing water in the Nanshan Tunnel, and it is concluded that the tunnel in the karst area is easy to gush and the water is very large. (2) The water volume of the Nanshan Tunnel is calculated and the results of the water inflow are analyzed. It is concluded that the right hole of the Nanshan Tunnel is more susceptible to surface water. (3) It is found that the predicted value is consistent with the initial period of the Nanshan Tunnel through the three-dimensional numerical simulation, which indicates that the parameter selection is reasonable and the numerical simulation method is feasible.
