摘　　要：窗井是地下建筑自然防排烟系统的配套构造,但在现行防火设计标准中对窗井净宽无明确规定,造成窗井设计的争议性和多样性。参考部分地方标准和图集对窗井的要求,结合地下楼梯间所在位置,利用Pyrosim软件对火灾烟气在窗井内蔓延规律进行量化分析与计算,为窗井设计提出更科学和合理的依据。Window well is a supporting structure of natural smoke control system of underground building,but there is no clear definition of the clear width of window well in the current fire protection design standard,resulting in the controversy and diversity of window well design.According to the requirements of some local standards and atlas for window well,combined with the location of the underground stairwell,Pyrosim software is used to conduct quantitative analysis and calculation of the spread law of fire smoke in the window well,which provides a more scientific and reasonable basis for the window well design.

关 键 词：窗井净宽 火灾蔓延 自然排烟 数值模拟
