摘要
国内外疏散时间的计算方法各异,同一建筑不同算法的计算结果相差较大,给实际工程计算带来不便.在介绍了国内外常用的3种工程算法后,对各类算法的适用范围与局限性做了比较分析,结合广州某体育馆进行各层疏散时间的计算,并用Legion仿真软件对这3种算法的计算结果进行了比对分析,得出行程时间法更符合实际情况的结论,建议我国建筑标准采用行程法作为疏散时间的工程计算方法.同时对日后疏散时间工程计算的研究提出了新的思路,并在国内首次对"安全区域"给出了具体的定义,具体标定了算法中的参数,为工程计算提供参考依据.
The domestic and foreign evacuation time＇s calculation method varies,the result of different algorithms for calculating the same building is different,so bring inconvenience for the actual engineering calculation.Based on three kinds of algorithms,this paper makes comparative analysis to each kind of algorithm＇s applicable scope and limitation,combining with a gymnasium for the calculation of evacuation time on each floor,and comparing the results of the three algorithms with the simulation software Legion,the conclusion that traveling time method is more realistic is obtained,the results suggest that our country building standard uses the traveling time method as engineering calculation method.Meanwhile,this paper proposes some new ideas for future research on evacuation time＇s engineering calculation method,and gives the concrete definition on ＂safety zone＂,demarcates the algorithm parameter,which provides a reference for the engineering calculation.
