Abstract

This article presents a comprehensive survey of the seismic impact experienced by urban tunnels, with a specific focus on the Line 7 of the Tehran Metro. Employing finite element software during Phase 2 of modeling, the study investigates the potential effects of seismic activity on tunnel stability. The research involves a meticulous examination of concurrent factors, primarily alterations in earthquake acceleration values and adjustments to the depth of the tunnel. The findings reveal that effective maintenance practices within the underground Metro Stations play a crucial role in minimizing the seismic impact on tunnel stability. The study underscores that the key mitigation strategy involves enhancing the structural integrity and reinforcing the conditions under which the tunnel is maintained. By doing so, the article suggests that urban planners and engineers can contribute significantly to the overall resilience and safety of underground metro systems in seismic-prone regions, such as Tehran.
