| Abstract: | The paper adopts the fire simulation software FDS to establish the model of tunnel fire,and contrast the experiment 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. |
