| Abstract: | With ANSYS software, plane elastoplastic model and three-dimensional linear elastic model are established to simulate the construction process of Nandaohe double-arch tunnel in this paper. Then it analyzes the stress and distortion change rules of surrounding rock and supporting structure, as well as analyzes the spatial change rules of excavated surface during the construction herein, the interaction between the construction of right and left tunnels and deformation and stability of the mid-partition wall, all of which provide scientific basis to design and construction of soft rock double-arch tunnel. |
