摘　　要：利用火灾模拟软件FDS建立隧道火灾模型,将温度场的模拟数据与实验数据进行对比,验证了模拟的准确性,然后对各种风速风向条件下隧道火灾工况进行模拟,通过对各种条件下的模拟数据的对比分析,得出风速风向因素对火灾时竖井型自然通风隧道内温度场影响规律。The paper adopts the fire simulation software FDS to establish the model of tunnel fire, and contrast the experi- ment data and simulated data of temperature field to prove the veracity of simulation. Then this paper simulates the fire conditions of a variety of wind velocity and direction conditions, and make a series of comparative analysis of simulated data to obtain the impact that velocity and direction make on temperature field in the natural ventilation tunnel with vertical shafts.
