Abstract
In order to research the fire properties in the tunnel with openings on roof, full-scale tests of tunnel fire were designed and conducted. The variation laws of smoke temperature and smoke propagation are gained, for example, the temperature at different distance from the fire source varies with time. Those tests data were analyzed with MatLab software and the laws of smoke were gained, such as the temperature under the ceiling of different distance from the fire source varying with longitudinal distance, temperature at the safety height varying with longitudinal distance from the fire source, as well as smoke longitudinal propagation laws and sedimentation laws. Bases on the theoretical analysis of the tests data, the security of the natural ventilation in tunnel fire was evaluated and the corresponding solutions were presented. Scientific gist was offered for future tunnel construction with natural ventilation.
