Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Interferometric synthetic aperture radar (InSAR) processing is widely implemented to remotely inspect linear infrastructure, such as railway tracks, enabling a wide range of spatiotemporal coverage. Despite InSAR is nowadays integrated with other remote sensing data and in situ measurements to establish structural health monitoring systems of railway ...

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.The time‐dependent deformation due to creep in simply supported girders represents a key controlling factor for the long‐term service performance of ballastless tracks. Accordingly, establishing the correlation between girder deformation and long‐term track irregularity provides the theoretical basis for the safety assessment of track structures ...

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.Derailment accidents of high‐speed trains (HSTs) occur occasionally. How to enable derailed vehicles to decelerate and come to a stop as much as possible along the track alignment is the last line of defense for mitigating the losses caused by HST derailment disasters.

Temperature Features of CRTSII Slab Ballastless Track in Severe Cold Region
DEStech Transactions on Engineering and Technology Research, 2017 Damages, such as slab end warped, gaps of slab and bed, and cracks of track bed, of CRTSII Slab-Ballastless-Track (SBT) in high speed railway were studied for temperature changing significantly in severe cold regions. First, Contact-Thermal- Resistance (CTR) between Concrete-Asphalt (CA) mortars of the SBT and roadbed were defined.
