Abstract

In order to study on the basic mechanical characteristics of CRTS III type slab ballastless track structure, a product of independent research and development of China, we have established the spatial mechanical model of elastic and non-elastic cushion of CRTS III type slab ballastless track based on the large universal finite element software ANSYS. And we have calculated respectively the spatial mechanical characteristics of CRTS III type slab ballastless track under vertical train load, temperature gradient load and the coupling load of these two. The result shows that under temperature gradient load, track structure stress significantly increased when the model have inelastic cushion, the tensile stress of self-compacting concrete increases from 2.07MPa to 7.0MPa.This shows that: elastic cushion can significantly reduce the effect of temperature load on the track structure. Under these 3 conditions, the stress of track structures are less than its allowed stress.
