地铁车站公共区楼扶梯处空间优化研究

Research on Space Optimization of Escalator in Public Area of Subway Station

本文结合郑州地铁5号线市第二人民医院站车站公共区楼扶梯处空间设计实践,研究地铁车站公共区楼扶梯处空间优化的方法。在结构设计安全的基础上,提出增大楼扶梯处开孔长度、优化换乘梯处结构板厚、增大换乘节点楼梯处中间平台净空高度等优化思路,并基于消防疏散安全的要求对公共区疏散楼梯的位置进行了优化分析。经过优化后的车站站台层乘用空间更加通透,乘客换乘更为便捷,缓解换乘梯处因层净空高度带来的压抑感,更好地体现地铁车站设计的人性化。以期为后续地铁车站的空间设计提供参考。

Combined with the design practice of escalator space in the public area of the Second People's Hospital Station of Zhengzhou Metro Line 5,this paper studies the optimization method of escalator space in the public area of the subway station.On the basis of the safety of the structure design,the optimization ideas such as increasing the opening length at the escalator of the building,optimizing the thickness of the structural plate at the transfer ladder,and increasing the clearance height of the middle platform at the transfer node stairs are put forward,based on the requirements of fire evacuation safety,the position of evacuation stairs in public areas is optimized and analyzed.After optimization,the passenger space on the platform floor of the station is more transparent and more convenient for passengers to transfer,which alleviates the sense of depression caused by the clearance height of the transfer ladder and better reflects the humanization of the subway station design.In order to provide a reference for the subsequent space design of subway stations.
