Dynamics-driven signal enhancement and local-global learning for track interlayer void diagnosis

The accurate identification of interlayer gaps within the Cement Asphalt Mortar (CAM) layer of CRTS II ballastless tracks is consistently hampered by intense high-speed background vibrations and the inherent non-stationarity of fault-induced signals. Conventional data-driven approaches often struggle to reconcile the...
