摘　　要：由以往的研究可见,重型载货车(HGV)隧道火灾热反馈效应显著。由于热反馈效应可能会影响隧道内的整体热释放速率和温度分布,因此隔热板可通过改变隧道内的热反馈效应影响隧道火灾。本文旨在研究隔热板在隧道火灾中发挥的作用,以评价保温板对隧道整体放热率和隧道温度的影响。Existing research findings showed that heavy goods vehicle(HGV)tunnel fire has obvious heat feedback effect,which may influence the overall heat release rate and temperature distribution in the tunnel,so heat isolation sheet could influence tunnel fire by changing the heat feedback effect in the tunnel.This paper analyzed the role of heat isolation sheet in tunnel fire,to evaluate the influence of heat insulation sheet on the overall heat release rate and tunnel temperature.
