Ballastless track, Temperature field, Damage tendency.Abstract
The three-dimensional transient thermal analysis technology of ABAQUS is used to analyze the temperature field and temperature stress characteristics of CRTS Ⅲ ballastless track with thin layer of asphalt concrete under the typical climatic conditions of summer and winter in seasonal freezing area due to the influence of heat transfer such as solar radiation, wind speed and temperature amplitude. The results show that the temperature distribution of track structure is nonlinear along the vertical direction, and there is a lag phenomenon; After adding asphalt concrete layer, the temperature of Subgrade under the layer is reduced, which has a good heat insulation effect; Asphalt concrete layer is more prone to interlayer damage in winter than in summer.
