Spatial–Temporal Model to Identify the Deformation of Underlying High-Speed Railway Infrastructure

Railway track geometry is generally understood to be influenced by the deformation of the track infrastructure. This study developed a spatial–temporal identification model for the deformation of the underlying high-speed railway infrastructure, including simply supported beams and track slabs based upon track geometry data collected between 2016 and 2019. To achieve this, we first preprocessed the data, including data collection and cleaning....
