铁路隧道避难所防烟风速研究
Wind speed of smoke control system in railway tunnel shelters
摘要：
以某铁路隧道避难所为研究对象，通过铁路隧道数值模拟，研究了铁路隧道防灾救援疏散工程火灾通风防灾系统，探讨了避难所防灾通风控制技术，分析了主隧道送风风速、避难所防烟风速等对烟气蔓延及控制效果的影响，为铁路隧道救援疏散工程防灾通风安全提供技术支撑。

Abstract：
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.
