Abstract

This paper established mechanical analysis model of track structure including rail, track slab, door type tendon, self-compacting concrete and base according to the CRTSIII track slab structure characteristics, and analyzed the force condition between interface of track slab and self-compacting concrete under different loads. After a series of laboratory testing, obtained the bonding strength between track slab and self-compacting concrete, ranged from 0.736MPa to 1.76MPa, and analyzed the cause of the gap of slab edge, gap of slab center, gap under rail by compared it with the theoretical calculation value. Results show that the negative temperature gradient loads is the main cause leading to the gap of slab edge and the corner of slab is most vulnerable while the train loads and the positive temperature gradient loads are the main causes of the gap of slab center and gap under rail, and the position of 1.0m away from the longitudinal of slab center and the edge of end-slab under the rail are most likely to get gap.
