为提高地铁内涝应急处置能力，对国内外地铁挡水技术和装置进行研究。针对地铁车站出入口、风亭风 井、正线、车辆基地等地铁内涝风险点，系统梳理国内外地铁挡水技术和挡水装置，分析地铁挡水装备的适用场 景以及优缺点；探讨地铁挡水装置在成本经济性、智能化与自动化以及可持续性等问题上面临的挑战，提出结构 优化与材料改进、多功能挡水装置、智能化与自动化控制、绿色技术与可持续发展等方面的建议。研究结果表明： 不同挡水装置应用场景不同，应针对不同风险点位以及涝水特点正确选择挡水装置；地铁常规挡水装置应用广泛， 技术相对成熟；新型技术在自动化方面有所突破，可以节省人力，提高应急可靠度。研究成果旨在为地铁挡水装 置的设计、安装和应用提供参考，为保障地铁系统的安全运行和有效应对地铁内涝提供技术支撑。

To enhance the emergency response capability of subway waterlogging, this study investigated water-barrier technologies and devices for subways, both domestically and internationally. A systematic review of conventional and innovative subway water-barrier technologies and devices was conducted, focusing on subway waterlogging risk points such as station entrances/exits, vent shafts, main tracks, and vehicle depots. The advantages and disadvantages of various subway water barrier technologies and devices were analyzed. This study discusses the challenges faced by subway water barrier technologies and devices in terms of cost economy, intelligence, automation, and sustainability. Recommendations are provided for structural optimization, material improvement, multifunctional water barrier devices, intelligent and automated control, green technology, and sustainable development. The results indicate that different water-barrier devices are suited to various application scenarios. Water barrier devices should be selected based on risk points and flood characteristics. Conventional subway water barrier devices are widely used and are technologically mature. Compared with these technologies, new technologies have advantages in terms of automation, resource-saving, and improved emergency reliability. This study aims to serve as a reference for the design, installation, and application of subway water-barrier devices, providing technical support for ensuring the safe operation of subway systems and essentially responding to subway waterlogging.
