Based on setting up the fire safety goals, performance criterion, fire scenario and uncertainty factor, this article simulated the occupants ’ evacuation time, smoke spread, radiation flow etc and determined fire detector and automatic extinguishing device by using the developed engineering method. and so these buildings ’ fire safety goals, which have the equivalent safety level with the existing national standard, can be achieved and those problems, which caused by some incompliment requirements or the existing codes not adapting to the practical need, can be solved
針對這類建築存在的典型問題，通過設定消防安全目標、確定性能判據、建立火災場景，考慮不確定因素，運用已開發的工程學方法對人員安全疏散時間、煙氣蔓延、輻射熱通量等進行模擬計算，對火災探測和自動滅火設施進行分析選擇，認為大型書城建築採用至少與現行國家標準的規定等效的方法來實現建築物的消防安全目標，能夠解決現行標準與實際需要不相適應或某些不完善的規定所帶來的問題。 -

Underground building with its closed, exits lacked, the people density being large, the flow direction of smoke and the spread direction of fire are consistent in the evacuation routes. fires in the underground building are much danger than over ground building. the hazards of smoke are especially strict in underground building, so smoke control in the underground building has becoming the focus
地下商業街由於其封閉性強，與地面直接連通的出入口少，內部通道的人流密度大，火勢蔓延的方向和煙氣流動的方向與人員疏散的方向相一致，因此一旦發生火災將產生比地上建築更為嚴重的後果，火災時煙氣危害將更為嚴峻，因此地下商業建築的煙氣控制研究越來越受到人們的關注。
