基于FDS模拟的某综合楼地下一层火灾烟气控制探讨

FDS-based Smoke Control Design in Underground Floor One of Comprehensive Buildings

针对地下建筑自身的特点,以某地下建筑为原型,运用FDS软件建立几何模型,通过模拟对该地下建筑有关防排烟的问题进行研究。选定了两个基本的火灾情景,即在未设置烟气控制系统和设置烟气控制系统两种情况下分别对该地下建筑进行火灾模拟,并结合模拟结果对烟气流动状况、火场温度等关键性指标进行了分析探讨,最后给出了合理化的建议。

This thesis uses FDS Version 4 to build up a detailed geometry model of a typical underground building to study the smoke exhaustion of the underground building.Taken into discussion in this thesis are two general fire sites,a site without ventilators and a site equipped with ventilators.Then it analyzes some key factors such as the smoke flow,temperature,and comes up with reasonable suggestions.
