Influencing Factors of Temperature Force and Displacement of Longitudinal Continuous Ballastless Seamless Turnout on Bridges for PDLs

Taking a longitudinal, continuous, ballastless turnout on LeiDa bridge on Wuhan-Guangzhou Passenger Dedicated Line (PDL) in China for instance, an integral finite element model of turnout (crossover)-track slab-bridge-pier was established, in which two No. 18 seamless turnouts with movable frog in form of crossover, longitudinal continuous Boegl ballastless track, bridges and piers were regarded as one system. The temperature force and displacement regularity of turnouts, track slab, bridges and piers were analyzed based on this model. Besides, their effect parameters were researched, such as extensional stiffness of track slab, friction coefficient of the slip membrane and the fixing of anchor point. Calculation results show that the new design of the longitudinal continuous Boegl ballastless turnout on bridge is feasible and could offer a theoretic reference guide for future design and application.
