摘要
隧道火灾随着通风风速和火灾规模不同 ,其温度场也发生了变化 ,本文对五种不同风速下的三种火灾规模进行了试验 ,研究了火区内和火区下游最高温度的变化规律、温度随时间的变化规律、温度沿隧道纵向分布规律、温度沿隧道横断面分布规律等 ,这对公路隧道防灾减灾设计有现实的指导意义。
The temperature field of fire in tunnel varies with the wind velocity of ventilation and fire scale, tests were carried out for three fire scales under 5 different wind velocities. The variation of maximum temperature, variation of temperature with time, distribution of temperature along the longitudinal of the tunnel, distribution of temperature across the cross section of the tunnel in and down to the region of fire are studied. It can serve as guide for disaster prevention and reduction design of highway tunnel.
