【摘要】：為評估隧道發(fā)生火災(zāi)時人員疏散安全,有必要準確計算隧道人員疏散時間。傳統(tǒng)經(jīng)驗公式法的假設(shè)條件過于簡單,而現(xiàn)有仿真模擬方法不能準確地模擬人的復雜行為。建立改進的經(jīng)驗公式法,通過隨機輸入計算參數(shù)來模擬隧道人員疏散的動態(tài)隨機過程,將疏散時間計算分解為多個階段,并考慮車輛及人員的隨機分布、火災(zāi)探測及人員反應(yīng)時間的計算、大客車乘客下車時間、人行速度的隨機輸入、以及隨人流密度變化的橫洞門通行能力等,使計算所得疏散時間更貼近實際。與其余方法對比分析表明,采用改進的經(jīng)驗公式法得到的計算結(jié)果與傳統(tǒng)經(jīng)驗公式計算方法相比,計算精度有較大提高。
[Abstract]:In order to evaluate the evacuation safety of tunnel fire, it is necessary to calculate the evacuation time accurately. The assumptions of the traditional empirical formula method are too simple, but the existing simulation methods can not accurately simulate the complex behavior of human beings. An improved empirical formula method is established to simulate the dynamic stochastic process of evacuation of tunnel personnel by random input of calculation parameters. The calculation of evacuation time is decomposed into several stages, and the random distribution of vehicles and personnel is considered. The calculation of fire detection and reaction time, the time of passengers getting off the bus, the random input of pedestrian speed, and the capacity of cross portal with the change of passenger density make the calculated evacuation time more practical. The comparison with other methods shows that the accuracy of the improved empirical formula method is higher than that of the traditional empirical formula method.
