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 ballastless track,bridges and piers were regarded as one system.
