Tunnel-Soil-Structures Interaction Effect due to Seismic Loading

In this work, the effect of the dynamical interaction between the superficial and the underground structures is studied under an impact of seismic loading. Finite element Plaxis2D code© under conditions of plane strain is used successfully. The material behaviour of the soil, the superficial structures and the tunnel is assumed to be fully elastic and are modeled with 15-nodes triangular element. The present study shows that increasing the number of neighboring structures and decreasing the separation distance between them can significantly reduce the seismic responses amplitudes of the superficial structures and the tunnel, especially in the case of soft soils. This reduction can reach up 35%. These results can be taken into consideration in the study and construction of realistic projects, especially sensitive ones.
