Wind speed of smoke control system in railway tunnel shelters

 Taking a railway tunnel shelter as the research object, through the numerical simulation of the railway tunnel, studies the fire ventilation and disaster prevention system of the railway tunnel disaster prevention and rescue evacuation project, discusses the disaster prevention and ventilation control technology of the shelter, and analyses the influence of wind speed of the main tunnel and the smoke control speed of the shelter on the smoke spread and control effect, which will provide the technical support for the disaster prevention and ventilation safety of the railway tunnel rescue evacuation project.
