摘要
基于Helbing运动算法对防护工程内人员在发生火灾时的疏散情况进行了仿真研究,以有效剂量分数的多气体毒性评价模型对人员的安全性做了评估。结果表明:由于人员拥挤、能见度的下降和烟气的毒性作用,使得人员在发生火灾情况下疏散速度大幅降低;随着走廊长度的增加,人员疏散的危险性呈幂指数性增加;自动报警系统缩减了人员反应时间,从而极大地提高了整个疏散过程的安全性,同时在自动报警系统情况下,人员疏散的危险性也是呈幂指数性增长的。
The personnel evacuation in protective engineering fire was simulated based on Helbing movement algorithm,and the safety of the personnel was assessed according to the Fraction Effective Dose （ FED） model. The results show that,the personnel evacuation speed was re-duced for the crowding, decreased visibility and toxicity effection of smoke. The risk of the personnel evacuation crease wit!i the lengthi of corridor. The automatic fire alarm reduced the reaction time of t!ie personnel,resulted in the improvement of the safetyof evacuation. In addition, with automatic fire ala rm,the risk of personnel evacuation also presented an corridor.
