大型公共建築物的防火設計一直是非常重要的研究課題，由於這類建築規模大、空間高、結構特殊、火災危險程度高，其消防設計在防火分區、安全疏散、煙氣控制、建築結構防火保護、主動消防設施設置等方面對傳統的「處方式」防火設計規范提出了挑戰。With analyzing of the case study and based on simulating and analyzing quantitatively, this article, considering the goal of the performance - based fire - protection design is protecting occupants from being injured and keeping buildings from being damaged, thought that fire compartmentation of a large building of saling books can be divided according to their saling malls and fire compartmentation in the saling mall can be separated by the fire - proof screen. on the evacuation design, the quantity of safety exits around these buildings and the evacuation width should be increased if possible and the safety exit number, exit width and evacuation distance can be determined according to the simulating results on smoke layer temperature and height, concentration of co2 and co, occupants evacuation time and visibility. on the means of preventing and discharging smoke, the most proper measure should be determined according to their geometrical characteristics and the natural means of discharging smoke is feasible to the large building of saling books. based on analyzing of smoke
通過對案例分析研究，本文認為大型書城建築性能化防火設計研究的最終目的是保證人員生命安全和保證建築結構安全，在模擬計算和量化分析的基礎上，大型書城的防火分區可以將中庭連通的書城區域劃分為一個區，在書城場地內可以採用防火卷簾進行防火分區劃分;在人員疏散設計中，應盡可能利用書城賣場的空間設計較多的安全出口和增大疏散寬度，其安全出口數量、寬度和疏散距離可以根據人員安全疏散時間和煙氣溫度、沉降高度、 co2濃度、 co濃度、能見度模擬計算結果驗證確定;在防排煙方式的選擇上，應當根據建築物的幾何特點選取最適宜的措施，就大型書城建築而言，採用自然排煙的方式是可行的。By using a zone model, simulates the behaviour of smoke temperature, height, volume fraction of co changing with time under different smoke control and extraction conditions in the station and introduces three critical conditions as a criterion for judging the effects of different smoke control and extraction methods
摘要運用區域模型模擬車站內不同防排煙工況下煙氣溫度、高度、 co體積分數隨時間的變化規律，以三項危險臨界條件是否實現作為衡量防排煙效果的判據。Presents the design of the air exhaust and smoke extraction systems for underground garages, including smoke control and fire zoning, design of the smoke extraction and air exhaust, and fire protection air make - up systems
摘要介紹了地下汽車庫的排風與排煙系統設計，包括防煙防火分區的劃分、排煙排風系統的設計以及消防補風系統。Taking dongzhimen station on beijing metro line 13 as an example, authors of the paper adopt cfd three dimensional simulation and one dimensional network simulation respectively to make a predictive analysis on the smoke distribution and air flow during a fire in accordance with the smoke suppression and exhaust system installed in the public area of the station and in the transit tunnels, and point out that the reliability of the smoke suppression and exhaust system is most important to guarantee the capability of passenger evacuation during a fire
摘要以北京地鐵13號線東直門站為例，結合車站公共區與區間隧道的防排煙系統設置情況，分別採用cfd三維模擬與一維網路模擬的方法，對火災時煙氣的分佈及氣流流動善進行預測分析，說明防排煙系統的可靠性對于保證火災情況下的安全疏散能力至關重要。The results show that only supplying air to platform stairs and simultaneously extracting smoke of fire zone can a best safe evacuation environment in the station be maintained
模擬結果表明，只有同時對站臺樓梯送風防煙和對火源所在防煙分區及時排煙，才能在車站內實現最有利於人員疏散的安全環境。In this paper, performance - based fire safety design concept was adopted to analyze fire safety objective of a underground bowling alley should achieve, fire scenarios were designed and the performance of water sprinkler and mechanical smoke evacuation system was studied by using zone model
