Resilience models for shield tunnels

Abstract:
Infrastructure tunnels are exposed to multiple hazards, threats and stressors, such as earthquakes, fires or floods, along with aging, and other stressors due to nearby constructing disturbances. The consequences of hazard occurrences pose a challenge to their resilience. Reliable fragility, restoration, and traffic reinstatement models are crucial for evaluating and quantifying tunnels’ resilience to evolving threats in complex transportation systems. Despite vulnerability and fragility of tunnels to hazards, being in the epicenter of research around underground structures over the last decade or so, tunnel recovery for quantifying resilience has been severely overlooked. Thus, that prevents operators from designing proactive and reactive adaptation measures to safeguard the seamless operations of tunnels. To fill this gap, this presentation delivers a restoration models to enable resilience quantification. The deterministic models are intended for practical applications.
