    Abstract
  • In order to study the reasonable arrangement scheme of embedded steel bars under different temperatures, a three-dimensional finite element model of continuous slab track was established. In the model, a surface based cohesive zone model (SCZM) was introduced and utilized to simulate the complex interaction between track slab and mortar layer in the process of shear failure, which was bonding-debonding-contact. Nonlinear constraint characteristic of shearing steel bars were also considered. Based on the model validated by the results of longitudinal shear test of slab track, shear behaviors of CA mortar layer were analyzed particularly. The results show that embedded steel bars can significantly improve interlayer shear performance of slab track. The increasing extent of temperature when interlayer is cracking increases from 10.5℃ to 30℃.It is suggested that the 16+8+8 arrangement scheme of embedded steel bars could be used when the temperature rise less than 20℃, and 16+16+16+10+8 is also proposed when the temperature rise at 20~30℃, Over 30℃, other measures should be used.
