摘　　要：综合管廊的电力运营输送安全是韧性城市的重要保证措施之一。在分析电力舱火灾成因、火灾特点及消防安全特殊性的基础上,归纳了综合管廊电力舱电缆火灾的关键科学问题。从电缆火灾的燃烧动力学机理、风险评估以及预警防护3个方面,综述了管廊电力舱火灾安全的研究成果和总体进展。结果表明:在电力舱电缆火灾的基础理论和实践应用上已经取得了较为系统的研究成果,但关于复杂廊体结构因素对火灾的影响研究还缺乏深入的探讨。结合管廊行业实际工程的发展,指出长通风区间电力舱电缆火灾的蔓延及联动防治是未来综合管廊消防系统研究的一个重要方向。The safe management of utility tunnel is crucial for re⁃silient cities.Analyzing the causes of power cabin fires,fire char⁃acteristics and the special measurements of fire safety,the key sci⁃entific issues of cable fires in utility tunnels are summarized.From the three aspects of cable fires,such as combustion dynamic mechanism,risk assessment and fire detection and protection,the overall progress of the research on power cabin fires in utility tunnels are summarized.The results show that the current re⁃search have been achieved in the basic theory and practical applica⁃tion of power cabin fires.However,there is a lack of in-depth dis⁃cussion on the impact of complex tunnel structural factors on fire development.The flame spread of cable fires in long ventilation compartments and effective fire prevention and automatic control are important issues for future research on utility tunnel fire pro⁃tection systems.
