| Abstract: | Research purposes: The analysis of the longitudinal mechanics behaviour of the ballastless slab track on long grade bridge under the effects of the temperature load and train load was made for providing the theoretical basis for the design of the long grade ballastless track. Research conclusions: The finite element method was used to set up a longitudinal integration calculation model of rail-track slab-bridge-pier based on the longitudinal interaction mechanism of line-bridge-pier,and the corresponding ge... |
