1、毕业论文（设计）题目商业建筑火灾烟气扩散流动分析学号姓名系队专业指导教师二○○八年六月本科毕业论文（设计）摘要随着我国商业建筑朝着现代化、大型化、多功能化方向不断发展，商业建筑火灾也呈现出上升趋势。基于商业建筑本身所具有的特点，一旦发生火灾就必然会产生大量的高温有毒烟气，给扑救工作和人员疏散带来很大的困难，容易造成重大的经济损失和人员伤亡事故。而烟气在商业建筑中的扩散速度越快，对其中人员的安全疏散影响越大，对人的生命安全威胁也越大，控制和消灭火灾的难度也就越大。因此，对商业建筑火灾烟气的扩散流动进行研
2、究，观察各种防排烟条件下烟气的流动情况,进一步揭示商业建筑火灾烟气流动的基本规律，以满足未来商业建筑防火设计的需要，对于消防部队在灭火救援和防排烟设计中具有积极的作用，从而不断降低火灾损失和人员伤亡。为了尽可能的克服烟雾带来的不利因素，本文从商业建筑火灾特点出发，对影响其烟气扩散流动的因素进行了分析，并针对其基本流动规律提出了控制方法，为消防部队组织人员疏散和扑救火灾提供参考。关键词火灾烟气;商业建筑;流动规律;分析与控制II本科毕业论文（设计）AbstractAsthecommercialbuild
