基于性能的既有交通枢纽防火改造研究

摘要

结合既有大型交通枢纽建筑的特点,分析了该类建筑在改建、扩建过程中的安全目标、消防安全原则与基本对策以及消防安全改造策略.选择具有代表性的工程案例,论述防火改造方面的设计难题,从保证人员安全、控制烟气蔓延、减少对运营的干扰等方面研究改造策略.%Based on the characteristics of existing large-scale trans-portation hubs,the safety target,fire safety principle and basic countermeasures,as well as the fire safety reforming strategy of the reconstruction and expansion of this kind of building was ana-lyzed.Selecting representative work case,the design problems of fire safety reforming were analyzed,and the reforming strategy was studied in points of ensuring staff safety,controlling smoke spreading and reducing the interference in operation.
