Diagnosis of high‐speed railway ballastless track arching based on unsupervised learning framework
Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 11, Page 1445-1465, 30 April 2025.Abstract Vehicle‐mounted detection methods have been widely applied in the maintenance of high‐speed railways (HSRs), providing feasibility for diagnosing ballastless track arching. However, applying detection data faces several key limitations: (1) The threshold mostly requires manual setting, making recognition accuracy highly subjective; (2) the ...
