Tunnel Fire Damage Assessment: A Review
Major tunnel fires can have catastrophic consequences, including loss of life, property damage, and long-term service disruptions. The rapid rise of gas temperature in excess of 1000 °C (1832 °F) inside a confined tunnel space as well as long fire duration due to limited emergency responder access necessitates special design considerations when evaluating the structural response to fire. Although tunnel stability is not challenged in most cases, severe damage to the concrete lining is observed after major fire events. This paper provides a detailed review of assessment methodologies and techniques of fire damage in concrete tunnel linings, including guidance on the determination of fire scenarios, concrete spalling, and tunnel safety from existing codes and guidelines, experiments, and numerical models. Based on the review, the need to developing relevant guidelines is emphasized, the knowledge gaps in the existing research are identified, and future research directions are proposed.
