中文摘要：

为了研究顶部开口的城市隧道在采用自然通风模式下的火灾特性,在已建成的隧道中设计并实施了全尺寸火灾实验,得到了隧道火灾自然通风模式下的拱顶附近烟气最高温度纵向变化数据。通过实验数据与理论预测结果对比的方式验证了H.Kurioka等人建立的隧道火羽流模型及其计算公式的可靠性,为市政公路隧道建设提供了科学依据,可以用来指导隧道火灾的研究及其消防工作的开展。

英文摘要：

In order to research the fire properties of the municipal tunnel with openings on roof, full- scale fire tests are designed and conducted in the built tunnel. The longitudinal diversification data of maximum smoke temperature are collected. The tunnel fire flame model and formula built by H. Kurioka is validated by comparing test data with theoretically predictive results, which afforded scientific gist for construction of municipal road tunnel and can be used for directing the research and fire protection work of tunnel fire.
