随着交通量的不断增大,隧道火灾发生的风险也在不断增大,对隧道路面火灾安全性的评价以及如何提高路面的火灾安全性成为了一个重要的问题,这也是目前管理、设计、施工、运营等部门面临的最重要的问题之一。因此,系统研究火灾对公路隧道路面的损害形式、机理以及公路隧道路面火灾高温下力学性能的变化,进而给出合适的隧道路面耐火方法是当前一项重要的任务,这对于提高公路隧道路面的火灾安全性具有重要的理论价值和实用意义。
With the continuous increase of traffic volume, the risk of tunnel fire is also increasing. It is an important issue to evaluate the fire safety of tunnel pavement and how to improve the fire safety of the pavement. At present, it is also an important issue to manage, design, Construction, operation and other departments facing one of the most important issues. Therefore, it is an important task to systematically study the damage form and mechanism of fire on pavement of highway tunnels and the change of mechanical properties under high temperature of pavement fires in highway tunnels, and then to provide appropriate tunnel pavement fire resistance method. Fire safety has important theoretical value and practical significance.
