The effect of the wheel load could cause the self-vibration effect of high frequency for the track slab. To analyze the fatigue characteristic of CRTS Ⅱ track slab under high-frequency load and the effect of the self-vibration of the track slab on its fatigue life, the fatigue characteristics of the track slab under the influence of this self-vibration during the interval in the wheelset was explored on the basis of existing fatigue damage criteria. The fatigue life of the track slab was predicted with reference to the effect of the de-bonding length, and the results obtained were compared with the results obtained when only the number of load actions was considered. Results show that, the possibility of damage to the track slab caused by the train wheel load is reduced when the track structure is intact. The bottom of the track slab would crack before resonance triggering occurred if the train speed was 360 km/h. When the track structure is intact, the self-vibration effect in the track slab caused by the wheel load has its greatest impact on the fatigue damage to the track slab, and the wheel load produces approximately 1.8 times the equivalent fatigue load to the track slab. The effect of the self-vibration effect in the track slab on the fatigue damage could be ignored when the slab de-bonding length is more than twice the distance between sleepers. When de-bonding length of the track slab is more than 3.2 times the distance between sleepers, it becomes difficult for the ballastless track on-site to maintain its expected 60-year service life.
