The Zhengzhou 27 Subway Station Under Fire Smoke Control Multiple Ventilation Mechanism Perfect Research

As an important facility of modern urban traffic, Metro has the characteristics of large passenger volume, high speed and accurate time. Therefore, in recent years, with the rapid development of urban rail transit construction in our country, the subway line length and passenger traffic volume have been increasing. But along with the development of subway traffic, fire accidents happen frequently. The subway with ventilation conditions, lighting conditions, characteristics of the internal environment is complex, fire safety evacuation and rescue work more difficult, so the fire safety design features of subway tunnel fire and tunnel has become a new research topic.
