    Abstract
  • For the mechanical deformation of longitudinally connected slab-type ballastless tracks under high-temperature load after maintenance measures were taken, the nonlinear constitutive relationship of bond stress-displacement at interfaces between track slabs and mortar layers and the nonlinear constitutive relationship of stress-slip in reinforcement anchor structure were considered, a finite element model for mechanical behavior analysis of longitudinally connected slab-type ballastless tracks was built, the nonlinear high-temperature load was applied to the model, and the influence laws of glue injection, reinforcement anchor installation, and 2 measures jointly used on the mechanical deformation and structural damage were compared and analyzed. Analysis results show that for the basic working condition with a 0.2 m interface seam on both sides of the track slab and a damaged wide and narrow joint, under the maintenance measures of glue injection, reinforcement anchor installation, and 2 measures jointly used, the maximum values of the interface seam at the end of the track slab adjacent to the damaged joint are 63%, 20%, and 18% of those before taking maintenance measures, and the maximum values of the compression damage of the damaged joint concrete are 51.0%, 6.8%, and 5.5% of those before taking maintenance measures. For the longitudinally connected slab-type ballastless track with a poor structural state of wide and narrow joints, the maintenance effect of reinforcement anchor installation is much better than that of glue injection, and the effect of using the two measures jointly is better. The effects of glue injection on limiting the vertical displacement at the end of longitudinally connected slab-type ballastless tracks, interface damage, and compression damage of wide and narrow joints increase with the increasing depth of glue injection. When only glue injection is taken, in order to reach the amplitude range of interface damage at the end of the track slab adjacent to the damaged joint when 2 measures are jointly used, the number of glue injection slabs shall not be less than 2, and the depth of glue injection on both sides shall not be less than 0.9 m. It is recommended to fully ensure the glue injection maintenance area when the glue injection is taken only.
