【摘要】：本論文采用文獻查閱、實地調研、數值計算、理論分析、軟件模擬、現場實驗相結合的方法對家具商城人員安全疏散進行系統(tǒng)研究。主要研究內容有：針對家具商城的特性選擇人員安全疏散的分析方法；運用相關規(guī)范的經驗公式計算和分析家具商城人員安全疏散參數；根據調研情況設置的四個典型疏散場景,采用FDS+Evac軟件模擬,而后進行疏散實驗,分析不同場景對人員疏散的影響。研究結果表明： 1.調研中發(fā)現家具商城一般嚴格按照國家規(guī)范來進行設計的,安全出口及樓梯凈寬度都是完全符合國家規(guī)定的。百人寬度指標可按實測最大人流計算,而相應減小安全出口凈寬度,從而減少經濟浪費。 2.疏散模擬得出的數據與疏散實驗得出的數據有一定差異,但反映了相似的線性規(guī)律：疏散人數與疏散時間成正比；疏散出口數量與疏散時間成反比。 3.疏散人員具有趨向性和選擇性,疏散出口的位置與相應出口的疏散人數有密切關系。表現在疏散人員傾向選擇方位較正、易明顯辨識的出口,所以明顯出口疏散人數較多,偏僻出口疏散人數較少。 4.在不同人流情況下,不同疏散出口對應的疏散人數和疏散時間具有相似規(guī)律；疏散出口的位置與相應出口的疏散時間關系不大；在疏散出口受阻情況下,人流量對疏散時間的影響不大。
[Abstract]:This paper uses the methods of literature reference, field investigation, numerical calculation, theoretical analysis, software simulation and field experiment to study the safety evacuation of furniture mall. The main research contents are as follows: to select the analysis method of personnel safety evacuation according to the characteristics of furniture mall, to calculate and analyze the safety evacuation parameters of furniture mall by using the empirical formula of relevant norms; According to the four typical evacuation scenarios, FDS Evac software was used to simulate the four typical evacuation scenarios, and then the evacuation experiments were carried out to analyze the impact of different scenarios on the evacuation. The results show that: 1. It is found that furniture shopping mall is designed strictly according to the national standard, and the safety exit and the net width of staircase are all in accordance with the state regulations. The index of 100 person width can be calculated according to the measured maximum passenger flow, and the net width of safety exit can be reduced accordingly, thus reducing economic waste. The data obtained from evacuation simulation are different from those obtained from evacuation experiment, but reflect the similar linear law: the number of evacuees is directly proportional to the evacuation time, and the number of evacuation exits is inversely proportional to the evacuation time. Evacuation personnel have tendency and selectivity, and the location of evacuation exit is closely related to the number of evacuees at the corresponding exit. It shows that the evacuees tend to choose the exit with positive orientation and easy to identify, so there are more evacuees in the obvious exits and fewer evacuees in the remote exits. 4. In the case of different flow of people, the number of evacuees and the time of evacuation are similar; the location of the exit is not related to the evacuation time of the corresponding exit; when the exit of evacuation is blocked, The flow of people has little effect on evacuation time.
