Research on the Deformation of Tunnel with the Influence of Seepage Water after Excavation
This paper discusses a tunnel whose entrance region is the main engineering background. Based on tunnel geological exploration report, we make the model. By establishing model and using numerical simulation software SIGMA/W and COMSOL to simulate the distortion in seepage condition, we find as tunnel excavation goes on, the pore water pressure of tunnel changes and it leads to infiltration of water in the tunnel, and the deformation of soil increases. The ground surface may sink if the evacuation goes on without taking actions, which is not safe for the buildings around. In case of this situation, the pore pressure of the tunnel around should be controlled from decreasing too fast. The result from our model is just like the result by monitoring measurement. The result shows the feasibility of software modeling in the prediction of tunnel seepage situation.
