| Abstract: | Using the tri-arch large-section tunnel in the metro section of Beijing subway, the paper establishes the model. It uses the finite element method to stimulate the construction of the tunnel and predicts the settlement. In particular, it makes a quantitative analysis of the settlement ratio of each step and draws up reasonable construction procedure and measures to decrease the settlement. |
