摘　　要：根据高层单元式住宅楼的特点建立典型的住宅楼模型,并利用FDS软件对其进行火灾数值模拟。分别选取卧室、客厅和厨房三个火灾场景对各房间、走廊和楼梯内的温度场、CO摩尔分数及能见度的分布进行数值模拟分析,得出各自的分布规律。火后单元内的温度、CO摩尔分数和能见度指标都在短时间内超过人体所能承受的极限值,起火单元内的人员应在第一时间尽快疏散。一个单元内部发生火灾,其他单元的人员的疏散主要受能见度的影响。The FDS was used to simulate a typical residential apartment building fire.Three fire scenarios （bed room,sitting room and kitchen） were modeled.The temperature and CO density and visibility of every room and corridor and stairway were simulated and the distribution regulation of them was obtained.The results showed that the temperature and CO density and visibility exceeded the limit of human endurance quickly,the people in fire unit should evacuate immediately.People affected by visibility mostly when fire happened in the other unit.
