Abstract

This paper studied on the fatigue experiment of two CRTSIII slab ballastless tracks on subgrade under high-speed train load, one was the track structure with self-compacting concrete thickness of 70 mm (the 70's), the other was 90 mm (the 90's). The two tracks were made of 1:1 full-scale test models and were carried out 3million times fatigue load test respectively. The experimental results show that the self-compacting concrete thickness greatly affects the track structural stress. Based on track structures with different self-compacting concrete thickness, self-compacting concrete and base concrete stress were analyzed comparatively. The research results provide guiding significance for the practical production.
