Abstract

The paper proposes a three-dimensional numerical model able to catch the main deformation patterns of the soil and of an underground tunnel structure subjected to non-uniform seismic shaking. The proposed 3D FE model for instance, investigate the effect of the non-uniform seismic loading condition due to the wave passage along the longitudinal axis of a tunnel and a comparison between the uniform and non-uniform case is proposed both in terms of free field and soil-structure interaction analysis. The numerical results show the non-negligible effect of wave passage on the tunnel structure compared with the uniform case. The dynamic increment of the transversal component of the internal tunnel forces is higher if the asynchronism is considered, in function of the shear waves velocity of propagation in the bedrock. In addition, longitudinal components of the internal forces arise on tunnel, i.e. longitudinal normal force, horizontal bending and shear force acting in the horizontal plane along the structure.
