| Abstract: | The finite element method is used to simulate the construction process of a twin-arched tunnel which is located near a steep slope. The variety law of stress and deformation of the surrounding rock and the supporting structure in the construction process are presented, and the effect of different construction sequences on the deformation and the stress is discussed. |
