摘要
通过参考国内外有关研究资料,并结合过往项目情况,对高速公路隧道内火灾特点及火灾对隧道衬砌结构的损害机理进行分析,并以洞内燃烧3h作为基本条件对隧道结构火灾工况下的受力情况进行分析,从而判定衬砌结构在高温后是否仍能满足适用要求。
In this paper,being based on both domestic and foreign related research data,as well as the past projects,characteristics of fire and mechanism of its damages to tunnel lining structure have been analyzed,and on the basis of three hours burning conditions,stress of tunnel structure in fire conditions has been analyzed,so as to determine whether the lining structure after high temperature could be still to meet the requirements of application.
