| Abstract: | By taking the submerged section of Nanjing Yangtze River crossing tunnel as an example, the internal forces and deformation of immersed tube tunnel subjected to seismic and dead loads are calculated respectively by using the plane strain finite element method. On this basis, the total internal forces of the lining are obtained by using superposition method. The calculation results can be referred to the design of immersed tube tunnels. |
