Abstract

It was fully considered that the necessity of introducing reliability, availability, maintainability and safety (RAMS) management into urban subway permanent way infrastructure management in this study and a RAM evaluation model is established for urban subway permanent way infrastructure management. According to 11 times of track inspection vehicle inspection data of 10 line unit sections on Beijing Subway Line 1 from January 2019 to December 2020, based on statistical and parameter fitting analyses, taking the track irregularity as an example, the reliability level calculation model was solved and the reliability level was calculated. The results indicated that the proposed model can be well applied to the management of urban subway permanent way infrastructure.
