深埋地下人员密集场所电梯与楼梯协同疏散的电梯运行参数研究

Elevator Operation Parameters during Elevators and Stairs Collaborative Evacuation in Deep Underground Personnel-Intensive Places

随着经济社会的高速发展,城市核心区域各类深埋地下人员密集场所不断涌现,传统的楼梯上行疏散已经很难满足其整体疏散的需求。为探索深埋地下人员密集场所电梯与楼梯协同疏散过程中电梯运行参数对疏散时间的影响规律,以重庆沙坪坝地下综合交通枢纽为研究对象,利用Pathfinder疏散模拟软件建立了沙坪坝地下综合交通枢纽人员疏散模型,对比研究了134种疏散场景下电梯运行参数对疏散时间的影响程度。结果表明:电梯运行参数中,电梯开关门时间对疏散时间的影响最大,电梯加速度对疏散时间的影响最小;电梯运行参数对疏散时间的影响程度从大到小排序为电梯开关门时间、电梯额定最大速度、电梯荷载和电梯加速度。

With the rapid development of economy and society,the deep underground personnel-intensive places are constantly constructed,so the traditional staircase evacuation is difficult to meet the overall evacuation needs.In order to explore the influence of elevator operation parameters on the evacuation time during the elevator and staircase coordinated evacuation in deep underground personnel-intensive places,this paper takes Chongqing Shapingba underground comprehensive transportation hub as the research object,and establishes the evacuation model by using the evacuation simulation software Pathfinder,and compares the influence of elevator operation parameters on evacuation time in 134 scenarios.The results show that elevator door opening-and-closing time exerts the greatest influence on evacuation time and elevator acceleration does the least.Less and less influence of elevator operation parameters on evacuation time is from door opening-and-closing time,elevator load,elevator rated maximum speed to elevator acceleration.
