In order to enhance the emergency response capability to subway waterlogging, this research investigated the water barrier technologies and devices for subways both domestically and internationally. Focusing on subway waterlogging risk points such as subway station entrances/exits, vent shafts, main tracks, and vehicle bases, a systematic review of conventional and innovative subway water barrier technologies and devices was conducted. Analyzed the advantages and disadvantages of various subway water barrier technologies and devices. This research discussed the challenges faced by subway water barrier technologies and devices in terms of cost economy, intelligence and automation, and sustainability. Recommendations were provided for structural optimization, material improvement, multifunctional water barrier devices, intelligent and automated control, green technology, and sustainable development. The research results indicate that different water barrier devices have different application scenarios. The water barrier devices should be selected by risk points and flood characteristics. Conventional subway water barrier devices are widely used and technologically mature. Compared to them, new technologies have advantages in automation, resource-saving, and improving emergency reliability. The research 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 effectively responding to subway waterlogging.
