- Aiming at the juncture defects of CRTS slab ballastless track in China high speed railway, an on-line monitoring system for temperature field and deformation of track slab was set up.The temperature variation and the relative displacement between slabs and junctures were obtained in real time. Experiments showed that the relative displacement of wide and narrow juncture could reach 0.11mm and 0.70mm caused by the temperature change of the track slab,which was the main reason for junctures'destruction. The linear correlation coefficients between the relative displacement and the temperature of the junctureswere 0.870 and 0.946,which could provide references for maintenance and repair of ballastless track.
