A more reasonable method of semi-infinite foundation analysis was realized in this paper through the introduction of viscous-spring artificial boundary to simulate the radiation damping and elastic recovery performance of the foundation. The viscous-spring artificial boundary is realized by Combine14 element in ANSYS finite element software to realize the real dynamic characteristics of complex rubber-soil foundation under dynamic loading. Firstly, the reliability of the method is verified by comparing the method with the example of numerical solution. Finally, the optimal tunnel shape is obtained by combining the rubber-soil foundation with different shapes of tunnels.
