Wide Juncture Cracking Effect on the CRTS II Slab Track

Abstract:

The CRTSⅡ slab track is one of the major ballastless tracks in China. Factors of the design, the construction, the train load and the service environment lead to the wide juncture cracking. The beam-solid model on the elastic foundation was established to carry out the mechanics analysis. Theoretical analysis was made on the influence of the depth and the length of the cracking on mechanical properties of the CRTS Ⅱ slab track. The train load and temperature load can make the increase of the warping of the slab that cause the irregularity of the slab track. When the wide juncture crack completely, the sudden chill can make the slab track crack and effect the quality of ballastless tracks.
