高铁站房改扩建工程人员安全疏散模拟研究

Simulation on safety evacuation in reconstruction and extension projects of high-speed railway station

以高铁站房改扩建工程为背景,运用Pathfinder软件进行建筑施工人员和站房工作人员及旅客的安全疏散模拟。建立三维安全疏散模型后,根据施工工况和站房运营情况确定疏散人群的数量和属性参数,选择符合实际的疏散人群行为模式,针对复杂施工环境下的站房内人群设置疏散方案进行模拟,并通过分析人员密度和楼梯通行人数对原疏散方案进行了优化。研究结果表明,保障疏散楼梯的畅通无阻和积极的疏散引导可有效地提高疏散效率。

Based on the reconstruction and expansion project of the high-speed railway station,the Pathfinder simulation software was used to simulate the safety evacuation of the builders in the construction and station staff and passengers.After establishing a three-dimensional safety evacuation model,the number and property parameters of the evacuation crowd were determined according to the construction conditions and the station operating conditions,and the behavior pattern of evacuation crowd was selected in accordance with the actual conditions.The evacuation scheme was simulated for the crowd in the complex construction environment,and the original evacuation scheme was optimized by analyzing the personnel density and the number of staircases.The application results showed that unobstructed evacuation staircase and active evacuation guidance could effectively improve the evacuation efficiency.
