摘要
为科学制定地铁区间疏散时列车车门开启方案,采用基于社会力模型的Legion行人仿真模型,研究地铁区间侧向平台疏散模式下,开启首节车厢第1扇车门、前2扇车门、前3扇车门和全部4扇车门4种工况下,对疏散过程及结果的影响。研究表明:开启首节车厢第1扇车门与其他开启方式的疏散时间相差不大,区间疏散时可仅开启第1扇车门;车厢内大约有80%的乘客是通过第一节车厢第1扇车门疏散出去的,组织区间疏散时应做好该处车门的客流疏导工作;当开启多扇车门进行疏散时,乘客选择通过第一节车厢进行疏散的效率可能更高。
In order to scientifically develop plans for door opening in metro tunnel evacuation,pedestrian simulation Legion model,developed based on social force models,was applied to study influence of door opening on evacuation process and results.The studies were conducted under mode of side platform evacuation for four cases,namely opening the first door,first two doors,first three doors and all four doors of the first carriage.The results show that evacuation time for opening the first door is similar to that of other cases,which means just opening the first door during interval tunnel evacuation is feasible.It is also found that about 80%of passengers in carriages are evacuated through the first door,so it is important to disperse passenger flow at this door when organizing interval evacuation.As multiple doors are opened,evacuation efficiency will be probably higher if passengers choose evacuate through the first carriage.
