- The interface bond damage between the slab and self-compaction concrete is one of the most common damages of CRTSIII slab track. According to the CRTSIII slab track structure characteristics, an finite element mechanical analysis model of track structure was established, which include rail, track slab, door type steel, self-compaction concrete and base. Furthermore, the influence of interface bond damage on the mechanical properties of CRTSIII slab track was analyzed. Results show that compared with interface in good condition, the stress of track structure increased with the increase of the length of interface bond damage. Among them, the range of interface vertical stress, track slab and self-compaction concrete stress remarkable increased. Under train load, the maximum increase range of track structure stress was up to 9 times compared with interface in good condition. Under temperature gradient load, the maximum increase range of track structure stress was up to 2.4 times compared with interface in good condition. Under train and temperature gradient coupling loads, the maximum increase range of track structure stress was up to 11 times compared with interface in good condition.
