Abstract

This paper presents studying the internal dynamic forces of the shallow box tunnels in dry sandy soils resulting from the seismic loads by adopting a two-dimensional numerical analysis according to the FEM method. The matter was modeled by adopting the plane strain case, flexible-with Rayleigh damping behavior for surrounding soil and elastic behavior for tunnel, it was found that the internal forces increase with increase width of the tunnel like for the thickness of the section and with increased density of the surrounding soil.
