考虑疲劳度与能见度的深埋地铁站人员疏散仿真

Simulated personnel evacuation of deep-buried subway station considering fatigue and visibility

依托某地下四层岛式地铁站工程,根据高峰期客流量确定疏散人数,模拟恒定速度下地铁站的人员疏散3考虑不同疲劳度、能见度条件,在已有人贞疏散实验的基础上,分6个场景利用Pathfinder对地铁站高峰时段客流进行疏散模拟。结果表明:常态下以恒定速度疏散时,人员整体疏散时间为10.4 min,列车及站台上的人员全部撤离站台所需时间为4.6 min;考虑疲劳度影响,人员全部疏散至地面的时间比恒定速度疏散多17.9 min。提高站台层至站厅层的能见度可以使总疏散时间减少约7 min。

Based on an underground four story island metro station project,the evacuation number was determined according to peak pavssenger flow and the evacuation from subway station with constant speed was simulated.Considering the different fatigue and different visibility,based on the existed evacuation experiments,6 scenarios was set in Pathfinder to simulate the evacuation from subway station at peak hours.The results showed that when evacuated at a constant speed under normal conditions,the overall evacuation time of personnel is 10.4 min,and the time required for all personnel on the train and platform to evacuate the platform is 4.6 min.Taking the fatigue effect into account,the time for all personnel to be evacuated to the ground is 17.9 min more than the evacuation time at a constant speed.The total evacuation time can be reduced about 7 minutes by improving the visibility from platform level to hall level.
