Research conclusions:(1)The seamless turnout scissors crossing ballastless track on bridge structure is complex， and should be combined with turnout details of bridge location relationship to calculate. ( 2 ) With the turnout to match I and III type elastic fastener system selection is reasonable.(3)Rubber gasket stiffness desirable to 250 kN/mm between shear cam and base plate. (4)Preference will be decorated on the symmetric structure of continuous beam，As arranged on asymmetric continuous beam，Should be combined with the specific circumstances choose reasonable type beam and bearing arrangement, Conducive to control the overall structure of the stress and deformation.(5)This paper studies for national railway，regional railway and urban rail transit construction provide a theoretical basis and has certain reference significance.
