Overview on safety management and maintenance of high-speed railway in China
Abstract As an important part of national security, railway safety is also an eternal theme in the development and maintenance of railways. In this study, to explore the establishment of high-speed railway geosubstructure safety indices and maintenance technology, worldwide typical design or maintenance standards and codes are summarized and compared, and theoerical analyses and testings are carried out to explore the high-speed railway safety indices and their influencing factors. The study indicates that it is scientifically valid and reasonable to use the management value of a track irregularity and the safety limit of a train as the railway safety indices for the construction standards of existing infrastructure. Complete and reliable technical standard systems, the standardized management of construction projects, and the adjustment and optimization of railways based on the real-time evaluation mechanism of the dynamic acceptance check provide the core support for determining China’s high-speed railway safety indices. Strategies for railway maintenance are proposed from the perspectives of a management system as well as detection and monitoring technology. Moreover, several new technologies for railway maintenance are discussed and the effects of these technologies are verified, providing a practical reference for railway safety management and maintenance.
