摘要
More than 20 years have passed since the three design standards for railway tunnels were published. In the meantime, design methods for structures other than tunnels have shifted to performance-verification design methods. Since 2014, a committee consisting of academic experts, railway operators has been set up to study the introduction of performance-based design, and as a result, in April 2022, the Ministry of Land, Infrastructure, Transport and Tourism issued the design standards for railway structures as a notification. This outlook commentary introduces trends in tunnel design technology for railways and an overview of new railway tunnel design standards based on performance-verification design methods. © 2023 Ken-yusha Inc..
