- An experiment that study on the dynamic characteristics of CRTS III slab track structure on roadbed under high-speed train load was carried out. The full-scale test model of CRTS III slab track structure had been established based on track-roadbed dynamic model test system. Test results show that after train load 7.2 million times, the stiffness of isolation layer increased by 1 time, while the performance of other parts of the track structure had little change. 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. Taking load action 0 million times, 200 million times, 400 million times and 600 million times for example, the displacement and stress of track structure could be calculated. Results show that test values and theoretical values are in good agreement.
