“…Further development of the wave problem of underground structures is given in [12,13]. Because analytical solutions are limited with simple geometry, simple boundary conditions, and simple behavior of materials, therefore, to calculate the SSS of complex underground structures, numerical methods are used, for example, the finite element method, the boundary element method, the finite difference method and other methods [14,15 ]. In this paper, we consider the dynamic calculations of the stress-strain state of shallowly laid tunnel structures with a circular outline (at a distance of fewer than 5 diameters from the day surface) under the influence of seismic loads.…”
