PAGE II 人防大厦火灾烟气控制对策 的应用研究 摘 要 随着我国国民经济和城镇建设的发展,我国城市发生了很大的变化, 正处于大发展、大建设阶段，一座座新的摩天大楼不断拔地而起，地下建筑工程也正在大量兴建，其城市建筑已朝大型化、高层化、多功能化的方向发展。在这样的建筑中，火灾所带来的危害和严重后果是以往那种小型、低层、单一化建筑根本无法相比的。高层建筑发生火灾，产生的烟雾是阻碍人们自救的最主要的因素，而且建筑中大量的可燃装饰材料，在燃烧过程中会产生大量的有毒气体。近年来，大量的火灾统计数字表明,火灾中受烟害直接致死的占80%以上, 因此,了解高层建筑防排烟装置和在火灾中的应用就显得尤为重要。 本文通过介绍人防大厦建筑概况，大厦固定防烟设施及大厦各个位置的防排烟设计，研究具体建筑的烟气流动规律和控制，固定防排烟装置和移动排烟装备在灭火当中的作用，以及提出火场烟气控制对策，从而为战斗员疏散物资，营救被困人员以及扑灭火灾等起到非常重要的作用。 关键词: 高层建筑 烟气 机械排烟 A research on application of smoke control measures in Civil Air Defense High-rise Building Abstract As Chinese national economic development and urbanization, Chinese cities have changed. At the moment, our country is in large development and construction phase, where blocks and blocks of new skyscrapers continued from where they stand, and a large number of underground construction works. Now the Large cities in China have been developed towards the construction of large-scale and high-level and multi-purpose. However, in such a construction, the fire brought about the harm and the serious consequences to the past that small, low-level, single building can not be compared to. To the high-rise building fire, smoke is the most important factor to impede self-help, and a large number of combustible building materials in the combustion process will produce a large number of toxic gases. In recent years, statistics show that a large number of fires, the fire directly affected by the death of smoking accounted for more than 80%. Therefore, smoke the control device settings of high-rise building for the scene of the fire escape is particularly important. In this paper, building civil air defense through the presentation of an overview of the building smoke fixed the location of facilities and building all of the smoke control design and study the specific architecture and control of flue gas flow, fixed installations and mobile anti-smoke exhaust equipment in which the role of fire, and make the fire smoke control measures, So i
