目前国内建筑物火灾损伤鉴定的研究主要集中在地面建筑物上,地下建筑物特别是隧道建筑物的研究几乎为空白;且隧道建筑火灾损坏的修复加固往往以凭经验偏安全大面积修补为主,其工程修复耗资大、工期长,有一定盲目性。随着今后隧道数量的增加,隧道将向长、大、深方向发展,同时石油产品运输也日趋增加,隧道火灾问题更加突出,隧道结构火灾损坏检定及其修复加固工作已普遍受到人们的关注。作者拟通过理论分析、室内试验、现场模拟试验和现场测试等一系列试验研究,对隧道衬砌结构火灾损伤评定,隧道衬砌灾后修复加固措施等问题作一些探讨。 At present, the research on fire damage identification of buildings in China mainly focuses on ground buildings. The research on underground buildings, especially tunnel structures is almost empty. The repair and reinforcement of fire damage in tunnel buildings is often based on large areas of safety and security , Its engineering costly repair, long duration, there is a certain blindness. With the increase of the number of tunnels in the future, the tunnels will develop in long, big and deep directions. At the same time, the transportation of petroleum products will also increase day by day. The fire problems of the tunnels will become more prominent. The fire damage detection of tunnel structures and its restoration and reinforcement work have generally attracted people’s attention. The author intends to discuss some issues such as fire damage assessment of tunnel lining structure and reinforcement measures of tunnel lining post-disaster through theoretical analysis, laboratory test, field simulation test and field test.
