摘　　要：采用理论计算和计算机模拟相结合的方法,研究了使用两种不同方式计算得到的扁平大空间建筑火灾烟气温度分布的特征和规律,并采用了将扁平大尺度空间划分为多个不同形式子单元的形式,对不同空间划分情形下火灾烟气温度和烟气层厚度的变化规律进行了研究,从而得出了扁平大空间建筑火灾烟气温度和厚度分布的规律,为研究此类建筑的烟气填充规律提供了一定的方法和思路。A new engineering method using CFAST was developed to predict the smoke movement in a flat large space based on theoretical calculation. The paper investigated changes of the temperature and the thickness of smoke in flat large space, which was divided the total space into some small subspace. Results show that this method can give more reliable smoke information than traditional simPle two - layer method in such kind of space.
