Analysis of tunnels seismic behaviour: Consideration of the structure geometry and site conditions

Tunnels are extremely important underground structures, the durability of which is paramount due to the high cost of their construction, which is undoubtedly tricky due to the encountered ground conditions, and which requires careful planning, particularly in seismic zones. These structures are susceptible to be damaged by earthquakes. Consequently, the study of their behaviour under the effect of seismic vibrations is of great importance. Thus, using an analytical method and two earthquake scenarios, this work aims to analyse the seismic behaviour of a tunnel located in northern Algeria, taking into account the geometry of the structure and the site conditions. The results, represented by fragility curves, show that the mechanical characteristics of the soil layers encountered have a remarkable impact on the behaviour of the tunnel under the effect of earthquakes.
