摘要
依据对隧道衬砌材料和构件进行实际烧损的试验成果，重点分析了不同火灾温度场与不同烧蚀时间对隧道衬砌力学性能的变化影响；在此基础上提出了隧道衬砌火灾损伤等级的划分标准与耐火极限时间。
Based on the experiments of really burning for the tunnel lining materials and members,variety of machanics property of the tunnel lining under the conditions of different fire temperature and different burning time are mainly analyzed.Then,the divide standard of damage grade and the enduring fire limit time of the tunnel lining caused by fire accident are discussed.
