Abstract: | In this paper, according to the needs of super close tunnel construction deformation monitoring, the spider moun- tain tunnel construction period vault subsidence deformation monitoring and prediction method are introduced. And, the hy- perbola regression function prediction model is established through experimental data to predict the interval of reaching sta- bility state of the tunnel vault sink, and to provide accurate standard to the health of the tunnel construction later. |

Keywords: | super close tunnel vault sink subsidence monitoring hyperbolic model |
