结合国道主干线南昌绕城公路上一盖板通道发生的火灾案例,主要开展了盖板通道的火损评价、加固设计及施工技术研究。希望研究成果能为今后公路通道、涵洞或隧道等混凝土结构的火损评价与加固设计及施工提供有利的借鉴。
Combined with the case of a fire on a covered channel in Nanchang Ring Road on the national trunk road, the study mainly focuses on the fire damage assessment, reinforcement design and construction technology of the covered channel. It is hoped that the research results can provide a good reference for the future fire damage assessment and reinforcement design and construction of concrete structures such as roadways, culverts or tunnels.
