The embedded channel technology avoids the phenomenon of structural damage caused by drilling, making it not only quick and convenient to install, inexpensive overall, simple to maintain, and construction time-saving. As a result, in recent years, China’s underground rail transit has seen a gradual maturation and wide application of construction technology. The embedded channel, which is a novel form of construction, is likely to experience fatigue fractures during the operation of rail transit owing to repetitive loading, which would cause structural collapse. Therefore, it is crucial to research its fatigue characteristics. At the moment, more research on the mechanical characteristics of embedded channel has been conducted both at home and abroad, but there are still few studies on the fatigue properties of embedded channel. As a result, the 30/20 embedded channel bare components are used as the study object in this work, and they are endurance tested. The results of the tests reveal that the specimen fatigue number exceeds 1.2 million times, which meets the standard of 100 years of service life. The study’s findings can serve as a guide for using embedded channel in urban rail transit.
