This paper reviews the fire problem in critical transportation infrastructures such as bridges and tunnels. The magnitude of the fire problem is illustrated, and the recent increase in fire problems in bridges and tunnels is highlighted. Recent research undertaken to address fire problems in transportation structures is reviewed, as well as critical factors governing the performance of those structures. Furthermore, key strategies recommended for mitigating fire hazards in bridges and tunnels are presented, and their applicability to practical situations is demonstrated through a practical case study. Furthermore, research needs and emerging trends for enhancing the “state-of-the-art” in this area are discussed.

本文回顾了关键交通基础设施（例如桥梁和隧道）中的火灾问题。说明了火灾问题的严重性，并着重指出了桥梁和隧道火灾问题的最新发展。审查了为解决运输结构中的火灾问题而进行的最新研究，以及控制这些结构性能的关键因素。此外，还介绍了推荐的缓解桥梁和隧道火灾危险的关键策略，并通过实际案例研究证明了它们在实际情况中的适用性。此外，还讨论了增强该领域“最新技术”的研究需求和新兴趋势。
